Description

An insufficient input validation vulnerability in the RTSP service of MERCURY MIPC252W v1.0.5 Build 230306 Rel.79931n allows an unauthenticated remote attacker to render an individual TCP connection temporarily unusable via sending an RTSP request with a Content-Length header but no corresponding message body. The affected RTSP parser enters a body-waiting state instead of rejecting the malformed request, causing all subsequent data on the connection to be silently consumed as body content until a server-side timeout closes the connection.

Technical Analysis

CVE-2026-51599 describes an insufficient input validation vulnerability in the RTSP service of MERCURY MIPC252W v1.0.5 Build 230306 Rel.79931n. The RTSP parser incorrectly handles requests that include a Content-Length header without an accompanying message body, entering a state where it waits for the body indefinitely. This causes the affected TCP connection to be rendered temporarily unusable as subsequent data is consumed silently until a timeout occurs, effectively causing a denial of service on that connection. The vulnerability can be triggered by an unauthenticated remote attacker.

Potential Impact

An unauthenticated remote attacker can cause a denial of service by making an individual TCP connection unusable temporarily. This disrupts legitimate RTSP communication on that connection until the server-side timeout closes it. The vulnerability impacts confidentiality, integrity, and availability as indicated by the CVSS vector, but the primary practical impact is denial of service on the affected connection.

Mitigation Recommendations

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or workaround is currently documented. Until a patch is available, consider limiting exposure of the RTSP service to untrusted networks and monitor for abnormal connection behavior.
