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

Application : JAF CMS
version: < 1.5.2
URL  : http://wordpress.org/
Description :

WordPress is a very popular personal publishing platform aka blog
software, and is used by everyone from celebrities, to government
officials, to non technical average joe's. 
---------------------------------------------------------------------------

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.
