Vulnerability Details : CVE-2017-3199
The Java implementation of GraniteDS, version 3.1.1.GA, AMF3 deserializers derives class instances from java.io.Externalizable rather than the AMF3 specification's recommendation of flash.utils.IExternalizable. A remote attacker with the ability to spoof or control an RMI server connection may be able to send serialized Java objects that execute arbitrary code when deserialized.
