CVE-2017-3200

Name of the Vulnerable Software and Affected Versions: GraniteDS version 3.1.1.G GraniteDS version 3.1.1.GA

Description: The Java implementation of AMF3 deserializers used in GraniteDS may allow instantiation of arbitrary classes via their public parameter-less constructor and subsequently call arbitrary Java Beans setter methods. The ability to exploit this issue depends on the availability of classes in the class path that make use of deserialization. A remote attacker with the ability to spoof or control information may be able to send serialized Java objects with pre-set properties that result in arbitrary code execution when deserialized.

Recommendations: For GraniteDS version 3.1.1.G, consider disabling the deserialization of Java objects until a patch is available. For GraniteDS version 3.1.1.GA, consider disabling the deserialization of Java objects until a patch is available. As a temporary workaround, restrict access to the deserialization functionality to minimize the risk of exploitation.
