CVE-2026-35902 Details
Description
The RTSP service of MERCURY IP camera MIPC252W 1.0.5 Build 230306 has an issue handling failed Digest authentication attempts. By repeatedly sending RTSP requests with invalid authentication parameters, an unauthenticated attacker can cause the RTSP service to enter a persistent authentication failure state, preventing legitimate clients from authenticating and leading to a denial of service.
A denial-of-service vulnerability has been identified in the RTSP service of the MERCURY IP camera model MIPC252W, running firmware version 1.0.5 Build 230306. The issue arises from the RTSP service's improper management of failed Digest authentication attempts. An unauthenticated attacker can exploit this flaw by repeatedly sending RTSP requests with invalid authentication parameters. This exploitation causes the RTSP service to enter a persistent authentication failure state, which blocks legitimate clients from authenticating. As a result, the vulnerability disrupts normal RTSP operations and access to the camera's video stream, leading to a denial-of-service condition.
