CVE-2017-3201: Exadel Flamingo Amf-Serializer

High severity, CVSS 8.1. EPSS: 5.4% chance of exploitation in the next 30 days.

The Java implementation of AMF3 deserializers used in Flamingo amf-serializer by Exadel, version 2.2.0 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.
