Unauthenticated remote code execution via EventCoordinator deserialization
Published Feb 11, 2021 · Updated Aug 4, 2024
Deserialization of untrusted data in Qognify Ocularis 5.9.0.395 allows remote attackers to execute arbitrary code via the EventCoordinator endpoint. The endpoint accepts serialized objects without proper validation, enabling attacker-controlled object deserialization and code execution in the Windows SYSTEM context. No authentication or user interaction is required, so any network-reachable EventCoordinator service can be fully compromised.
