/*
Vuln Explanation:

Take a look on one of the admin files, the begin should be something like this:

<?php
include("config.inc.php");
if(!isset($_COOKIE['admin']))
{
header("Location:index.php");
}
?>

this is not a protection for two reasons:

i) everyone can make a cookie with false credentials
ii) there isn't any exit or die function after header('Location: index.php')

Now look at create engine.php, and you find that there isn't any parse of the
text you send as the engine name..

Besides that the names of the tabs are written into a PHP files to make faster
the loading process.. the only limit we have while we inject the code is taht we
can't put spaces in the code, otherwise php will end with an error..
