'Name'=> 'Sun Java Web Start BasicServiceImpl Remote Code Execution Exploit',

'Description' => %q{

This module exploits a vulnerability in Java Runtime Environment

that allows an attacker to escape the Java Sandbox. By injecting

a parameter into a javaws call within the BasicServiceImpl class

the default java sandbox policy file can be therefore overwritten.

The vulnerability affects version 6 prior to update 22.

NOTE: Exploiting this vulnerability causes several sinister-looking

popup windows saying that Java is "Downloading application."
