§ DeluxeBB 0day Remote Change Admin's credentials §

------------------------------------------------------------------------------------------------

nexen

------------------------------------------------------------------------------------------------

PoC / Bug Explanation: 

When you update your profile,

DeluxeBB execute a vulnerable query:



$db->unbuffered_query("UPDATE ".$prefix."users SET email='$xemail', msn='$xmsn', icq='$xicq', ... WHERE (username='$membercookie')");



So, editing cookie "membercookie" you can change remote user's email.



Enjoy ;)
