CVE-2013-2423
LowCVSS 3.7KEVSummary
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. Oracle has not commented on claims 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.
Risk Assessment
A remote attacker could execute untrusted code with elevated privileges, potentially disabling the security manager and taking control of the Java application.
Recommendation
Update Oracle Java SE and OpenJDK to the April 2013 patch level or later and restrict the execution of untrusted Java applets and applications.

Original NVD description (English source)
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.
