Affected Software:              phpBB 2
Software Version:               2.0.* - 2.0.10
Software URL:           http://www.phpbb.com

Attack:                 SQL Injection, allowing people to minipulate the query into pulling data
                        they should not previously be able too obtain. (Such as passwords)
                        Arbituary EXEC allows you, if you can get on to a new line, to execute
                        your own PHP, which can be fatal.

Description:            Because of the way urldecode and magic quotes works,
                        it turns %2527 into %27, which is a single quote, and it
                        leaves it unslashed. This gives you a SQL Injection, leading
                        to arbituary PHP exec hole. But because you can't get outside
                        preg_replace because of magic quotes, this is very very useless.
