Re: webgoat breaking

["Jeff Williams @ Aspect" <jeff.williams () aspectsecurity com>]

Hi,

The challenge is intended to be very difficult (and in some cases
tedious), like penetrating systems in the real world.  But it's definitely
achievable with patience and thought.  I've always said your best pentest
tool is in your head.

Anyway, you can solve the authentication stage by figuring out how to
access the source code and then just checking the logic.  You're right
that it is not based on SQL.  Another solid reason for code review, but
that's another thread.  There is another way to get the credentials by
sniffing the network, but it's not realistic in most environments and was
intended to teach a different skill.

As far as defacing the site using the SSI vulnerability, you'll need to
learn the SSI syntax and then look for a command you could inject and use.
I'm sure you can execute the attack if you think hard.  The code can also
be your guide if you figured out how to access it.  Of course you could
cheat and extract it from CVS, but it is available through a separate
weakness in WebGoat.

Good luck,

--Jeff

hi all,

i m trying to break the webgoat challenge. But i m not able to break the
user authentication. I tried to break user authentication using all
possible
SQL Injections, but it couldnt work out. I need help on this topic. what i
should try to break this user authentication. i have gone thru its code
,it
is written in the java & i did not find any Sql query used for cheking
username & password, so is there any way to break this user authentication
scheme ?
I m looking for the material on SERVER SIDE INCLUDES VULNAREBILITIES. i
got
the information that some sites are vulnarable to Server Side Includes but
i
dont know how i can use SSI to test vulnarability of the sites.  SSL
includes can be helpfull in webgoat also.Any help on this topic will be
highly appreciated.



Thanking You.
Sincerely,
