CVE-2017-3207: WebORB for Java by Midnight Coders, version 5.1.1.0, Action Message Format (AMF3) Java implementation is vulnerable to insecure deserialization

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.

Security readout for executives and security teams

CVE-2017-3207 is a deserialization flaw in Midnight Coders WebORB for Java 5.1.1.0. If an attacker can spoof or control an RMI server connection used by the application, serialized Java objects may execute code during deserialization. The source bundle does not show active exploitation or a confirmed vendor patch. Exposure is likely limited to environments running Midnight Coders WebORB for Java 5.1.1.0 with AMF3 Java deserialization and RMI-dependent integrations. Systems not using WebORB for Java, not using AMF3 deserialization, or unable to reach attacker-controlled or spoofed RMI servers are less likely to be exposed. Treat as high priority where legacy WebORB for Java 5.1.1.0 supports production workflows. The business risk is code execution, but urgency depends on whether RMI connections can be spoofed or controlled. Prioritize inventory and containment first because patch details are not established in the bundle. Mitigation focus: Inventory WebORB for Java deployments and identify version 5.1.1.0.; Check Midnight Coders or maintainer guidance for fixed versions or configuration advice.; Restrict RMI connectivity to trusted, authenticated, necessary endpoints only..

Deserialization of Untrusted Data

Deserialization of Untrusted Data represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
