CVE-2023-38958Network attack vector

Unauthenticated door control via crafted web requests

Published Aug 3, 2023 · Updated Jul 9, 2026

Incorrect authorization in ZKTeco BioAccess IVS 3.3.1 allows remote attackers to open or close managed doors through crafted web requests. The public disclosure identifies the door-control web interface but does not identify the endpoint or authorization check that accepts the request. No authentication or user interaction is required, and exploitation changes the physical lock state of doors controlled by the platform.
