CVE-2023-50219Network attack vector

Authenticated code execution via RunQuery deserialization

Published May 3, 2024 · Updated Aug 2, 2024

Deserialization of untrusted data in Ignition 8.1.30 allows remote authenticated users to execute arbitrary code as SYSTEM. The RunQuery class deserializes user-supplied data without proper validation, allowing attacker-controlled objects to reach Java deserialization. Valid Ignition credentials and network access to the affected service are required, and successful exploitation grants SYSTEM-level code execution.
