RE: Looking for a Web Application Vulnerable to XSS Cookie Grab

["Michael Silk" <michaels () phg com au>]

Chuck,

        No it doesn't seem it is 'exploitable' in that you could use it
to take over the system, however it does allow you to observe the
attempts of XSS and how you could use that against someone viewing the
code (in this case: yourself). I'd suggest that the point of HacMe bank
is not to take down the system (after all, it's installed on your server
...) but to learn about what to do - this lets you do that.

Mark,

    Thanks for the response and thanks for writing a great learning
tool.

    Maybe I am just not doing something right, but it looks to me like
the Stored XSS is not really exploitable because a given user will never
see another user's posts to the message board.  Am I missing something?
