9.8 · CRITICALOverview
CVE-2026-35903 is a critical-severity vulnerability affecting mercurycom mipc252w_firmware. It was published on April 27, 2026 and has a CVSS 3.1 base score of 9.8 (CRITICAL).
This vulnerability has a CVSS 3.1 base score of 9.8, rated CRITICAL. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
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.
Remediation
Check the references section for vendor advisories and patches from mercurycom. Update mipc252w_firmware to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
