SmartSiteCMS v1.0 authentication bypass

STATUS: I contacted the vendor more than 2 months ago and still no response.

TECHNICAL INFO
================================================================
One of the worst cms I've ever seen regarding security, no input sanitation
at all. Bypassing authentication just requires to create a cookie named 
"userName"

Vulnerable code:
admin.php line 43
--------------------------------
<?php
if (isset($_COOKIE['userName']))
{
--------------------------------

VULNERABLE VERSIONS
---------------------------------------------------------------
Ive only tested v1.0
