I’ve recently found this blog entry on a tool that writes XSS attacks directly to the database. It looks like a terribly good way to scan an application for weaknesses in my applications.
I’ve tried to run it on Mono, since my development platform is Linux. Unfortunately it crashes with a System.ArgumentNullException deep inside Microsoft.Practices.EnterpriseLibrary and I seem to be unable to find sufficient information about the software (it seems to be a single-shot project, with no homepage and no further development).
Is anyone aware of a similar tool? Preferably it should be:
- cross-platform (Java, Python, .NET/Mono, even cross-platform C is ok)
- open source (I really like being able to audit my security tools)
- able to talk to a wide range of DB products (the big ones are most important: MySQL, Oracle, SQL Server, …)
Edit: I’d like to clarify my goal: I’d like a tool that directly writes the result of a successful XSS/SQL injection attack into the database. The idea is that I want to check that every place in my app does correct output encoding. Detecting and avoiding the data getting there in the first place is an entirely different thing (and might not be possible when I display data that’s written to the DB by a third-party application).
Edit 2: Corneliu Tusnea, the author of the tool I linked to above, has since released the tool as free software on codeplex: http://xssattack.codeplex.com/
I think metasploit has most of the attributes you are looking for. It may even be the only one that has all of what you specify, since all the others I can think of are closed source. There are a few existing modules that deal with XSS and one in particular that you should take a peek at: HTTP Microsoft SQL Injection Table XSS Infection. From the sounds of that module it is capable of doing exactly what you are wanting to do.
The framework is written in Ruby I believe, and is supposed to be easy to extend with your own modules which you may need/want to do.
I hope that helps.
