Sun Java Web Start BasicServiceImpl Code Execution
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."
