CVE-2022-28173Network attack vector

Unauthenticated admin access via crafted messages

Published Dec 21, 2022 · Updated Apr 16, 2025

Access control in Hikvision DS-3WF0AC-2NT and DS-3WF01C-2N/O before fixed firmware allows remote attackers to obtain administrator permission through the web server. The server mishandles crafted messages and fails to enforce authorization on the affected request path. No authentication or user interaction is required, so a network attacker can gain administrative control with confidentiality and integrity impact; the records do not document a specific availability effect.
