This module abuses the Color Management classes from a Java Applet to run
|
|
arbitrary Java code outside of the sandbox as exploited in the wild in February
|
|
and March of 2013. The vulnerability affects Java version 7u15 and earlier and 6u41
|
|
and earlier and has been tested successfully on Windows XP SP3 and Windows 7 SP1
|
|
systems. This exploit doesn't bypass click-to-play, so the user must accept the java
|
|
warning in order to run the malicious applet.
