Description

This module exploits a vulnerability in the Java Runtime Environment
that allows an attacker to run an applet outside of the Java Sandbox. When
an applet is invoked with:

1. A "codebase" parameter that points at a trusted directory
2. A "code" parameter that is a URL that does not contain any dots

the applet will run outside of the sandbox.

This vulnerability affects JRE prior to version 6 update 24.
