CVE-2026-31256: n/a
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.
AI Analysis
Technical Summary
This vulnerability affects the RTSP service of the MERCURY MIPC252W device running firmware 1.0.5 Build 230306 Rel.79931n. When the device processes a SETUP request for the path rtsp://<IP>:554/stream1/track2, it fails to properly validate the Transport header field. If the Transport header is improperly constructed, the RTSP service dereferences a NULL pointer during parsing, causing a crash and automatic reboot of the device. This is a denial-of-service condition triggered by malformed RTSP requests. No CVSS score or patch information is currently available.
Potential Impact
Successful exploitation causes the affected device to crash and reboot automatically, resulting in a denial-of-service condition. There is no information indicating code execution or data compromise. The impact is limited to service disruption of the RTSP functionality on the affected device.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, consider restricting access to the RTSP service from untrusted networks to reduce exposure. Monitor vendor channels for updates regarding patches or mitigations.
