An attacker who has authenticated to the device can send a series of SETUP requests targeting the same media track within a single RTSP session. The server misprocesses this pattern, resetting the RTSP connection. This results in a denial\u2011of\u2011service condition that can interrupt live video streams or voice services. The weakness is categorized as uncontrolled resource consumption (CWE\u2011400).", "risk_and_exploitability": "The CVSS score of 4.4 indicates a low\u2011moderate impact. The EPSS score is not available, and the vulnerability is not listed in the CISA KEV catalog, suggesting limited evidence of exploitation. The attack requires valid authentication to the RTSP service and the ability to send repeated SETUP requests; once the pattern is detected, the server will restart the session, creating a DoS. Because no patch is currently available, the risk remains present until a firmware update is released."}}}}, "created": "2026-04-28T09:17:39.113380+00:00", "title": "Repeated RTSP SETUP Request Causing Session Termination in Mercury MIPC252W", "updated": "2026-04-28T13:30:32.083884+00:00", "vendors": ["mercury", "mercury$PRODUCT$mipc252w"]}
