|
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."
