Apr 27, 2026MERCURY MIPC252W IP camera 1.0.5 Build 230306 Rel.79931n contains an improper authentication vulnerability in the RTSP service.CVE-2026-35903 · Other software · Mercurycom · reported by MITRECritical 9.8
MERCURY MIPC252W IP camera 1.0.5 Build 230306 Rel.79931n contains an improper authentication vulnerability in the RTSP service. After successful Digest authentication in an initial DESCRIBE request, the device does not verify the Digest response parameter in subsequent RTSP requests within the same session. As a result, RTSP methods such as SETUP, PLAY, and TEARDOWN can be processed even when the Authorization header contains an empty or invalid response value, as long as the nonce and session identifier correspond to a previously authenticated session. This allows an attacker with network access to reuse session parameters and issue unauthorized RTSP control commands without computing a valid Digest response.

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.

Apr 27, 2026A handling issue in the RTSP service of the Mercury MIPC252W 1.0.5 Build 230306 Rel.79931n allows an authenticated attacker to trigger session termination by reCVE-2026-35901 · Other software · Mercurycom · reported by MITREMedium 4.4
A handling issue in the RTSP service of the Mercury MIPC252W 1.0.5 Build 230306 Rel.79931n allows an authenticated attacker to trigger session termination by repeatedly sending SETUP requests for the same media track within a single RTSP session. This causes the server to reset the RTSP connection, leading to a denial-of-service condition.

Apr 27, 2026A null pointer dereference vulnerability exists in the RTSP service of the MERCURY MIPC252W 1.0.5 Build 230306 Rel.79931n.CVE-2026-31256 · Other software · Mercurycom · reported by MITREHigh 7.5
A null pointer dereference vulnerability exists in the RTSP service of the MERCURY MIPC252W 1.0.5 Build 230306 Rel.79931n. During the processing of a SETUP request for the path rtsp://<IP>:554/stream1/track2, the device fails to properly validate the Transport header field. When this header is improperly constructed, the RTSP service can dereference a NULL pointer during request parsing. Successful exploitation causes the device to crash and automatically reboot.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
