CVE-2017-3207 Information

Description

The Java implementations of AMF3 deserializers in WebORB for Java by Midnight Coders version 5.1.1.0 derive 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.
