Re: tools to scan source code

Hello all,

been watching this conversation closely as it is hugely relevant to me
at the moment.

I am just about to enter my final year of University, and I was hoping
to create a static source code analyser for ASP.net
applications......I thought it was a good idea, however after reading
this I am starting to think otherwise, and maybe there could be better
uses of the opportunity to complete a large project.

Does anyone have any advice?  I want to do a project involving
security and .net.   I've been recommend to do a application to edit
the http request - like WebScarab however this has been done many
times, and doesn't represent anything 'new'  and while source code
auditors aren't new, they are less readily available as open source
software.  This still is an option I might look into, and taking it
off on a tangent some how, and doing more of a full pen-test
application.

I welcome anyones advice.

Thank you

Ben

Hi Kish,

I realize I've been a bit too cryptic in my answer:

Yes, RATS _can_ audit PHP source. What I was referring to is that web
app vulnerabilities have a different structure than the vulnerabilities
you commonly audit C source code for.

For instance, you can detect candidates for buffer overflow (along with
a bunch of false positives) through simple regexp pattern matching. It's
way more difficult to detect with few false positives candidates for SQL
injection.

The fact that RATS is able to handle PHP code is not a synonym to the
fact that it can handle web-app vulnerabilities.
