CVE-2023-3638Network attack vector

Unauthenticated web access via response tampering

Published Jul 19, 2023 · Updated Jan 16, 2025

Improper authentication in GeoVision GV-ADR2701 1.00_2017_12_15 allows remote attackers to access the web application. The web login flow accepts a client-edited authentication response, allowing a failed result to be changed into a successful one. Network access to the camera web interface is sufficient; no credentials or user interaction are required, and the bypass exposes protected application functions.
