Intro: This code changes a user's password.
Body: While the code confirms that the requesting user typed the same new password twice, it does not confirm that the user requesting the password change is the same user whose password will be changed. An attacker can request a change of another user's password and gain control of the victim's account.
$user = $_GET['user']; $pass = $_GET['pass']; $checkpass = $_GET['checkpass']; if ($pass == $checkpass) { SetUserPassword($user, $pass); }
