Affected software description:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Application : JAF CMS
version: < 3.0 Final
URL  : http://jaf-cms.opensource-indonesia.com
Author : Salim "ph03y3nk"
Description :

JAF CMS - ...just another flat file CMS, is a Content Management System (CMS)
consist of a powerful set of PHP scripts that allow you to maintain personal
home page. There is no need for a database. The pages stored in a simple flat
file. I've coded this script because I realize that its hard to found server
(especially free space) offering PHP with database support already.

---------------------------------------------------------------------------

Vulnerabilities:
~~~~~~~~~~~~~~~~

A. Full path disclosure:

   A remote user can access the file directly to cause the system to display  
   an error message that indicates the installation path. The resulting error 
   message will disclose potentially sensitive installation path information 
   to the remote attacker.
