CVE-2023-1399

Privilege escalation via unsafe deserialization

Published Mar 27, 2023 · Updated Jan 16, 2025

Unsafe deserialization in Keysight N6854A Geolocation Server 2.4.2 and earlier allows local users to gain privileges and execute code. Public advisories do not identify the deserialization entry point, serialized object format, or unsafe decoding operation that processes attacker-controlled data. A low-privileged local account and the default configuration are sufficient; successful exploitation can run code with elevated rights and fully compromise the server.
