CVE-2024-42531Public exploitNetwork attack vector

Unauthenticated live-video access via crafted RTSP URIs

Published Aug 23, 2024 · Updated Jul 5, 2026

Improper input validation in EZVIZ CS-CV246 firmware 5.3.0 build 191225 allows remote attackers to access live video via crafted RTSP URIs. The RTSP request handler accepts a crafted sequence of valid URIs and redirects the camera feed without authenticating the requester. The vendor disputes the impact, stating that the published sample establishes RTSP communication but retrieves no video or audio.
