CVE-2026-31256: n/a
CVE-2026-31256 is a high-severity vulnerability in the RTSP service of the MERCURY MIPC252W device firmware version 1.0.5 Build 230306 Rel.79931n. The issue arises from improper validation of the Transport header field in a SETUP request, leading to a null pointer dereference. Exploitation causes the device to crash and reboot automatically. There is no information about an available patch or official remediation at this time.
AI Analysis
Technical Summary
This vulnerability involves a null pointer dereference in the RTSP service of the MERCURY MIPC252W device firmware 1.0.5 Build 230306 Rel.79931n. When processing a SETUP request with a malformed Transport header, the device fails to validate the header properly, causing the RTSP service to dereference a NULL pointer during request parsing. This results in a denial of service condition by crashing and rebooting the device. The CVSS v3.1 base score is 7.5, reflecting network attack vector, low attack complexity, no privileges or user interaction required, and impact limited to availability.
Potential Impact
Successful exploitation causes a denial of service by crashing and automatically rebooting the affected device. There is no confidentiality or integrity impact reported. The device becomes temporarily unavailable during the crash and reboot cycle.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, consider restricting access to the RTSP service from untrusted networks to reduce exposure.
