This Metasploit 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).
