This module exploits a vulnerability in Java 7, which allows an attacker to run
|
|
|
|
|
arbitrary Java code outside the sandbox. The vulnerability seems to be related to
|
|
|
|
|
the use of the newly introduced ClassFinder#resolveClass in Java 7, which allows
|
|
|
|
|
the sun.awt.SunToolkit class to be loaded and modified. Please note this flaw is
|
|
|
|
|
also being exploited in the wild, and there is no patch from Oracle at this point.
|
|
|
|
|
Our module has been successfully tested on multiple setups, including: IE, Firefox,

|
|

Chrome and Safari on Windows, Linux and OS X, etc.
