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.
