'Description' => %q{
This module exploits a vulnerability in Java 7, which allows an attacker to run
arbitrary Java code outside the sandbox. The vulnerability seems to be related to
the use of the newly introduced ClassFinder#resolveClass in Java 7, which allows
the sun.awt.SunToolkit class to be loaded and modified. Please note this flaw is
also being exploited in the wild, and there is no patch from Oracle at this point.
Our module has been successfully tested on multiple setups, including: IE, Firefox,
Chrome and Safari on Windows, Linux and OS X, etc.
