CVE-2021-26627Network attack vector

Unauthenticated live-video disclosure via RTSP requests

Published Apr 19, 2022 · Updated Aug 3, 2024

Improper access control in EDrhyme QCP 200W allows remote attackers to view live camera video through the enabled RTSP service. The camera's RTSP listener on TCP port 554 is enabled by default and serves live images without adequately authenticating the request. Network reachability to that port is sufficient; no administrator privileges or user interaction are required, and the reported consequence is viewing rather than modifying or interrupting the stream.
