 0x01 - Affected software description:

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

 ocPortal is the leader in community CMS and portal software for the web. 

 It allows you to create and configure your own website within minutes. 

 It's packed full of innovative features that you will not find in competing 

 software (such as support for multi-site networks, or flexible page view 

 permissions), taking a completely different approach to the mainstream 

 competition. ocPortal can seamlessly integrate with most major forum systems, 

 has an innovative point system for your members to enjoy, support for all your 

 content (downloads, banners, galleries, and more), the ability to add new pages 

 as easily as writing a text file, and produces robust and standard compliant 

 pages. No other CMS package can do all of that.  

                                                   // from ocportal.com







 0x02 - Vulnerability Discription:

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

 This vulnerability exists in index.php because there isn't a check for 

 path in $req_path variable. So we can change the path to some evil host were

 the funcs.php script is and we can even run some system command with the evil 

 script. I have mentioned that you can run system commands with evil script so

 this is very critical bug. I sugest you that you immediatly get new version 

 of this portal.

 





 0x03 - Vulnerability Code:

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

 Vulnerability code is at the beagining of index.php 



 ----- beging the code in index.php -----



  if (!isset($req_path)) $req_path="";

  require_once($req_path."funcs.php");



 ----- end of the code -----

 of this portal from http://ocportal.com/ 







 0x05 - Exploit:

 On your evil host you must put scipt funcs.php.

 0x006 - The End:
