Re: BBCode [IMG] [/IMG ] Tag Vulnerability

[Jan Kantert <Jan_Kantert () web de>]

There is a very similar trick: Often you also can take over PHP-session and get authentificated as another user, if you 
just log referers of an image loaded using [IMG][/IMG]. The user needs to have disabled cookies so that the PHPSESSION 
is set in URL. This can be done automatically using a little Perl/PHP-Script. You can use regex to parse out which 
useraccount you compromised. If it was an administrator or moderator you could delete posts or kick users.

Greetings,
Jan
