BobMarion writes " After a long talk the other night with DJMaze the code below will secure PHP-Nuke 7.5's module admins. DJMaze voiced his concern that my site might be open to those hacks so we brain stormed the quickest fix, NukeSentinel(tm) 2.1.0 carries this patch but since it is still a few days away I wanted everyone to secure their sites!

Place this at the begining of your admin.php after the opening < ?php tag, if your using NukeSentinel(tm) place it right after the opening < ?php tag in includes/sentinel.php instead.

if($aid AND (!isset($admin) OR empty($admin)) AND $op!='login') { unset($aid); unset($admin); }

Note: NukeSentinel(tm) 2.0.2 has been updated to include this fix. You only need to reupload the includes/sentinel.php file."
