'Description' => %q{
This module exploits a vulnerability in Java 7, which allows an attacker to run arbitrary
Java code outside the sandbox. This flaw is also being exploited in the wild, and there is
no patch from Oracle at this point. The exploit has been tested to work against: IE, Chrome
and Firefox across different platforms.
