CVE-2026-51599: n/a
An insufficient input validation vulnerability exists in the RTSP service of MERCURY MIPC252W v1.0.5 Build 230306 Rel.79931n. An unauthenticated remote attacker can send a malformed RTSP request with a Content-Length header but no message body, causing the RTSP parser to wait indefinitely for the body. This results in the TCP connection becoming temporarily unusable until a server-side timeout closes it.
AI Analysis
Technical Summary
CVE-2026-51599 describes a vulnerability in the RTSP service of MERCURY MIPC252W v1.0.5 Build 230306 Rel.79931n where insufficient input validation allows an unauthenticated attacker to disrupt an individual TCP connection. By sending an RTSP request containing a Content-Length header without the corresponding message body, the RTSP parser enters a body-waiting state instead of rejecting the malformed request. This causes all subsequent data on the connection to be consumed silently as body content, effectively rendering the connection unusable until a timeout closes it.
Potential Impact
The vulnerability allows an unauthenticated remote attacker to cause a denial of service on an individual TCP connection by making it temporarily unusable. This does not indicate broader service disruption or code execution but impacts availability of the affected connection until the server-side timeout occurs.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or workaround information is available at this time.
