The summary by CVE is:

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.

The weakness was released 04/16/2013 as Oracle Java SE Critical Patch Update Advisory - April 2013 as confirmed advisory (Website). It is possible to read the advisory at oracle.com. The identification of this vulnerability is CVE-2013-2423 since 03/05/2013. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Technical details are unknown but a public exploit is available.

A public exploit has been developed by metasploit and been published 1 weeks after the advisory. The exploit is available at exploit-db.com. It is declared as attacked. We expect the 0-day to have been worth approximately $25k-$100k. The vulnerability scanner Nessus provides a plugin with the ID 69742 (Amazon Linux AMI : java-1.7.0-openjdk (ALAS-2013-183)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Amazon Linux Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 350563 (Amazon Linux Security Advisory for java-1.7.0-openjdk: ALAS-2013-183).
