NoGe has reported a vulnerability in the Flash Tree Gallery component for Joomla!, which can be exploited by malicious people to compromise a vulnerable system.

Input passed to the "mosConfig_live_site" parameter in administrator/components/com_treeg/admin.treeg.php is not properly verified before being used to include files. This can be exploited to include arbitrary files from local or external resources.

Successful exploitation requires that "register_globals" is enabled.

The vulnerability is reported in version 1.0. Other versions may also be affected.

Solution
Edit the source code to ensure that input is properly verified.
