Nmap 6.40 [2013-07-29]
o [Nsock] Added initial proxy support to Nsock. Nmap version detection and
NSE can now establish TCP connections through chains of proxies. HTTP
CONNECT and SOCKS4 protocols are supported, with some limitations. Use the
Nmap --proxies option with a chain of one or more proxies as the argument
(example: http://localhost:8080,socks4://someproxy.example.com) [Henri
Doreau]
o [Ncat] Added --lua-exec. This feature is basically the equivalent of 'ncat
--sh-exec "lua <scriptname>"' and allows you to run Lua scripts with Ncat,
redirecting all stdin and stdout operations to the socket connection. See

fingerprints (if Nmap doesn't find a good match) and corrections (if Nmap
guesses wrong) are useful. [David Fifield]
o Updated the Nmap license agreement to close some loopholes and stop some
abusers. It's particularly targeted at companies which distribute
malware-laden Nmap installers as we caught Download.com doing last
year--http://insecure.org/news/download-com-fiasco.html. The updated
license is in the all the normal places, including
https://svn.nmap.org/nmap/COPYING.
o [NSE] Oops, there was a vulnerability in one of our 437 NSE scripts. If
you ran the (fortunately non-default) http-domino-enum-passwords script
with the (fortunately also non-default) domino-enum-passwords.idpath
parameter against a malicious server, it could cause an arbitrarily named
file to to be written to the client system. Thanks to Trustwave researcher
Piotr Duszynski for discovering and reporting the problem. We've fixed
that script, and also updated several other scripts to use a new
stdnse.filename_escape function for extra safety. This breaks our record
of never having a vulnerability in the 16 years that Nmap has existed, but
that's still a fairly good run! [David, Fyodor]
o [Nsock] Added initial proxy support to Nsock. Nmap version detection
and NSE can now establish TCP connections through chains of one or
more CONNECT or SOCKS4 proxies. Use the Nmap --proxies option with a
chain of one or more proxies as the argument (example:
http://localhost:8080,socks4://someproxy.example.com). Note that
only version detection and NSE are supported so far (no port
scanning or host discovery), and there are other limitations
described in the man page. [Henri Doreau]

limitations. It is implemented within the nsock library and thus has
no effect on the ping, port scanning and OS discovery phases. Only
NSE and version scan already benefit from this option. Also, SSL

resolving (hostnames are always resolved by nmap). In other words,
the current implementation does not aim to provide strong
