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.
