CVE-2023-3324

Data and service impact via unsafe BinaryFormatter deserialization

Published Jul 24, 2023 · Updated Oct 18, 2024

Unsafe deserialization in ABB Ability zenon 11 build through 11 build 106404 allows local users to alter host data and interrupt service. The zenon graphics utility's 3dRuntimeControl.dll uses deprecated deserialization functions or classes such as BinaryFormatter when the Service Engine opens a screen containing a specific WPF element. Exploitation requires low-privileged local access and user interaction; ABB does not identify the serialized input path or exact post-deserialization operation.
