CVE-2023-51629

Authentication bypass via hardcoded ONVIF PIN

Published May 3, 2024 · Updated Aug 2, 2024

Authentication bypass in D-Link DCS-8300LHV2 firmware 1.06.01 and earlier allows remote attackers to access the ONVIF API. The ONVIF API configuration accepts a hardcoded PIN instead of validating a device-specific credential, granting access to protected ONVIF operations. No credentials or user interaction are required, but reachability is limited to attackers on a network adjacent to the camera.
