Subject: BellaBook Admin Bypass/Remote Code Execution

#AUTHOR: ilker kandemir

Explanation:
The user verification routine used in most of the files is:
########################################################
#require_once('prefs.php');
#if (isset($_COOKIE['bellabuffs'])) {
# if ($_COOKIE['bellabuffs'] == md5($admin_name.$admin_pass.$secret)) {
# if (isset($_GET['ap'])) { $page = $_GET['ap']; } else { $page = ""; }
# include('header.php');
#
########################################################
So basically it's saying "If the value within the cookie pheap_login is not the same value
that is assigned to the $admin_name variable withing prefs.php then you have to be redirected
to the login page".
So if we know the $admin_name we can access any page that uses this authentication method. Also,
we can retrieve all credentials in clear-text.
