CVE-2025-70962 is an incorrect access control vulnerability in Zosi C519M firmware version V4.2.8.823C01450BA. The RTSP authentication mechanism uses hardcoded, unchangeable credentials, allowing authentication to succeed with embedded default credentials rather than administrator-defined secrets. Because the credentials cannot be changed, the affected device exposes its video stream to anyone who can reach the RTSP service and knows or obtains the built-in authentication values. The issue results in unauthorized access to live camera footage.
