'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.
