'Name'=> 'Java Applet JMX Remote Code Execution',

'Description' => %q{

This module abuses the JMX classes from a Java Applet to run arbitrary Java code

outside of the sandbox as exploited in the wild in February of 2013. Additionally,

this module bypasses default security settings introduced in Java 7 Update 10 to run

unsigned applet without displaying any warning to the user.
