CVE-2022-45424Network attack vector

Unauthenticated AES key disclosure via crafted request

Published Dec 27, 2022 · Updated Apr 14, 2025

Missing authentication in affected Dahua DSS products allows remote attackers to obtain an AES cryptographic key via a crafted packet. The exposed network interface processes the crafted request without authentication and returns the AES key, but Dahua has not identified the interface, request format, or key use. No account or user interaction is required; the documented consequence is key disclosure, with no reported integrity or availability impact.
