VERIFY ADVISORY:
http://secunia.com/advisories/39539/

DESCRIPTION:
A vulnerability has been discovered in the Webmoney WMI component for
Joomla!, which can be exploited by malicious people to disclose
sensitive information.

Input passed via the "controller" parameter to index.php (if "option"
is set to "com_wmi") 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-encode NULL
bytes.

The vulnerability is confirmed in version 1.5.0. Other versions may
also be affected.

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