HTTP: Oracle Java 7 Applet Remote Code Execution
This signature detects attempts to exploit a new vulnerability against Java 7. A successful attack can lead to arbitrary code execution. This vulnerability is currently being exploited in the wild and affects multiple browsers and platforms.
Extended Description
Multiple vulnerabilities in the Java Runtime Environment (JRE) component in Oracle Java SE 7 Update 6 and earlier allow remote attackers to execute arbitrary code via a crafted applet that bypasses SecurityManager restrictions by (1) using com.sun.beans.finder.ClassFinder.findClass and leveraging an exception with the forName method to access restricted classes from arbitrary packages such as sun.awt.SunToolkit, then (2) using "reflection with a trusted immediate caller" to leverage the getField method to access and modify private fields, as exploited in the wild in August 2012 using Gondzz.class and Gondvv.class.
