No base language's class libraries are a match for the rich programing
API that the GPL code base provides in this area, be it libwhisker,
WHArsenal, SPIKE Proxy, or any of the many other tools.
You probably could use the C#'s WebClient.Credentials Property to set
your credentials, then do some basic Whisker 1.0-style effort to build a
tiny scanner. However, I think that to do a professional job, you're
going to want to have a bit more control and a bit more stick behind
your spearhead, in the form of advanced features. The ability to write
custom checks with VulnXML, for example.
So I suggest one of three things:
1. Use APS with SPIKE Proxy (or some other application assessment tool
that can itself bounce through another proxy) APS is pure python and
GPL, so if I get a lot more requests for this functionality (feel free
to bug me at dave@immunitysec.com), I'll merge his code with SPIKE
Proxy's core. (To bounce SPIKE Proxy though another proxy, download
version 1.4.4, and use the -h and -H parameters to spkproxy.py)
2. Check out SPIKE 2.7, which includes NTLM buffer overflow tools and
brute forcers. (E.G, you can sniff a request that you want to fuzz, then
use SPIKE's much more fast and powerful fuzzing framework to find
overflows, format string bugs, SQL injection and the like - all through
NTLM authenticated requests). It also includes a transparent HTTP[S]
proxy (webmitm).
3. You can e-mail me and I'll send you the current SP 1.4.5 Beta, which
includes an ordering fix (so GET /a?a=b&c=d always is a=b&c=d and not
c=d&a=b) and a mod I whipped up this morning that lets you browse NTLM
pages through the proxy by passing the authentication back and forth a
bit. However, rewrite request and scanning functionality still don't
know about NTLM, and so that functionality won't be effective against
NTLM servers. For the record, the bug was not in SPIKE Proxy's handling
of Connection: Keep-Alive, but actually IE doesn't bother to respond to
WWW-Authenticate when it is set up to use a Proxy. So I changed
WWW-Authenticate to Proxy-Authenticate: and Proxy-Authorization to
Authorization and it worked. Integrating APS would have been a more
final solution, but that's slightly more than a few minutes' work.
