DESCRIPTION:
A vulnerability has been reported in the J!WHMCS Integrator component
for Joomla!, which can be exploited by malicious people to disclose
sensitive information.

Input passed via the "controller" parameter to index.php (when
"option" is set to "com_jwhmcs") is not properly verified before
being used to include files. This can be exploited to include
arbitrary files from local resources via directory traversal
sequences and URL-encoded NULL bytes.
