Vulnerability Details : CVE-2013-2423 (1 public exploit)

Unspecified vulnerability in the Java Runtime Environment (JRE) component in Oracle Java SE 7 Update 17 and earlier, and OpenJDK 7, allows remote attackers to affect integrity via unknown vectors related to HotSpot. NOTE: the previous information is from the April 2013 CPU. Oracle has not commented on claims from the original researcher that this vulnerability allows remote attackers to bypass permission checks by the MethodHandles method and modify arbitrary public final fields using reflection and type confusion, as demonstrated using integer and double fields to disable the security manager.

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.
