This module exploits a vulnerability in the Rhino Script Engine that  
can be used by a Java Applet to run arbitrary Java code outside of  
the sandbox. The vulnerability affects version 7 and version 6 update  
27 and earlier, and should work on any browser that supports Java  
(for example: IE, Firefox, Google Chrome, etc)
