DVWA Cross Site Request Forgery

Posted on 16 September 2014

<!-- There are multiple CSRF issues in DVWA. Attackers can use these CSRF exploits to
 first reset the DVWA database of victim, then make the victim log in using the default resets,
 next crafts another CSRF to change the challenge level to low to make exploitation more probable,
 then use these to craft a command execution CSRF and possibly get a shell. :)

 *This PoC will open calculator as a demo execution in approximately 5 seconds.*

 The attacker just needs to know you have DVWA for this to work.
