o [NSE] Raw packet sending at the IP layer is now supported, in addition to
the Ethernet sending functionality. Packets to send start with an IPv4
header and can be sent to arbitrary hosts. [Kris]
o [NSE] Added the ipidseq script to classify a host's IP ID sequence numbers
in the same way Nmap does. This can be used to test hosts' suitability for
Nmap's Idle Scan (-sI), i.e. check if a host is an idle zombie. This is
the first script to use the new raw IP sending functionality in NSE. [Kris]
o [NSE] Added the function nmap.is_privileged() to tell a script if, as far
as Nmap's concerned, it can do privileged operations. For instance, this
can be used to see if a script should be able to open a raw socket or
Ethernet interface. [Kris]
o [NSE] Added the function nmap.get_ports() to allow a script to iterate
over a host's port tables matching a certain protocol and state. [Kris,
Patrick]
buildGet/buildRequest with a one-step build_request. Provide a new
function generic_request that can do a request for any given method
(get, head, and post are now defined in terms of this function).
options table, in http functions. It was unreasonable that this
yet-unused feature was given a more prominent place than even the header
and request body, both of which are in the options table.
This change doesn't affect any other scripts or libraries because none
of them use cookies. In the cases, like http.get, where cookies was an
optional final parameter, I just removed it. Where it was not the final
parameter, as in http.post and http.pGet, I left the parameter in place
but documented that it is ignored for backwards compatibility.
make use of it. Added 5 scripts that use the new libraries:
- snmp-netstat shows listening and connected sockets
- snmp-processes shows process information including name, pid, path and
parameters
- snmp-win32-services shows the names of running Windows services
- snmp-win32-shares shows the names and path of Windows shares
- snmp-win32-software shows a list of installed Windows software
- snmp-win32-users shows a list of local Windows users
the script indicating where to download it if it is not available. Make
the script check whether the file is the normal binary from 5.20 or
before, or the XOR-encoded binary from 5.21.
it was returning an empty string, causing blank output entries for

there is one. Even though section 4.4 of RFC 2616 says that sending a
body in response to a HEAD request is a MUST NOT, pyllyukko sent me a
sample from a server that does--"LuCI - Lua Configuration Interface".
initial request to get a value stored in the Keep-Alive header, which is
the size of the pipeline. It then iterates, doignt hat many requests at
once until the list of requests is exhausted. The prbolem was that in
the first round, it didn't count its initial Keep-Alive probe. So if the
server said it was good for 40 requests, we would send 41 before closing
the connection. Even worse was when the initial probe returned a
"Connection: close"; the pipeline would try another request before
closing the connection for the first time.
failure. It happened when there was an error getting the a response
at the beginning of a batch in http.pipeline. The symptoms of the
bug were:
NSE: Received only 0 of 1 expected reponses.
Decreasing max pipelined requests to 0.
NSOCK (0.1870s) Write request for 0 bytes...
nmap: nsock_core.c:516: handle_write_result: Assertion `bytesleft > 0' failed.
The error was reported by Brandon Enright and pyllyukko.
parsing mostly. Response parsing is centralized, and fewer operations
are done on raw HTTP data.
The biggest user-visible change is that http.request goes back to
returning a parsed result table, not raw HTTP data. I believe this is
how the function worked in the past; it's what the NSEDoc for the
function says. The only thing that used http.request was citrixxml.lua,
and this commit alters it to match the new expectations.
The other change is that the http.pipeline function no longer accepts
the "raw" option. The only script that used that was sql-injection.nse,
and this commit modifies that script as well.
HEAD request. This makes it look like the response to the HEAD request
has a body. As a result, http-enum can wrongly surmise that HEAD
requests don't work when it hits a cache entry while testing HEAD.
