Penetration Testing: Re: hacker challenge... pwn3d login form

["Tyler Johnson" <tjohnson () novacoast com>]

Actually, you did it the hard way. If you register an account  (like 'test') and log in you'll find the cookie value is 
an md5 hash of your username (test = 098f6bcd4621d373cade4e832627b4f6 ). 

If you edit that value to be the md5 hash of 'admin' (21232f297a57a5a743894a0e4a801fc3) and refresh the page you're 
logged in as admin and presented with users and passwords.

Hi Jorge,

Did you say the cookie bit to throw people off? I notice that basically 
the cookie is using an md5'ed version of the username as the id, and I 
get that, but I actually got in by using the username "admin' -- /*" and 
the password "1".

Also, I have been able to exploit the search feature to get this 
information also by sending a query like this.

-99' UNION SELECT 1,2,username,password,5 FROM members -- /*

Kind Regards,

James
