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, patches, and mitigation guidance. 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.
