LokiCMS is a content management system that is designed to be simple and clear.
Most cms systems are way to complicated if you just want to make a small mostly static site,
LokiCMS allows you to make a simple site with a few clicks.

- Vulnerability:

Its possible for a remote attacker to set "CMS main settings" without admin privileges.
There is a logical weakness in "admin.php" which could result in multiple vulnerabilitis
simply by set "LokiACTION" and desired parameters via http POST method.
