Java AMF3 Deserialization Remote Code Execution Vulnerability

CVE-2017-3201 · MEDIUM Severity

AV:N/AC:M/AU:N/C:P/I:P/A:P

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.
