CVE-2023-1967Network attack vector

Remote code execution via unsafe deserialization

Published Apr 27, 2023 · Updated Jan 16, 2025

Unsafe deserialization in Keysight N8844A Data Analytics Web Service 2.1.7351 and earlier allows remote attackers to execute code. The service accepts untrusted serialized data without sufficiently validating the resulting data; the endpoint, serializer, and omitted validation are undisclosed. No authentication or user interaction is required, and successful exploitation executes attacker-controlled code in the service context.
