CVE-2023-50223Network attack vector

Authenticated code execution via unsafe ExtendedDocumentCodec deserialization

Published May 3, 2024 · Updated Aug 2, 2024

Deserialization of untrusted data in Inductive Automation Ignition 8.1.0 through 8.1.34 allows remote authenticated users to execute code. ExtendedDocumentCodec accepts attacker-controlled serialized Java objects without validating their types before reconstruction. Access requires privileged Gateway connectivity, and successful exploitation runs arbitrary code as SYSTEM on the Gateway host.
