CVE-2026-51601: n/a
Tenda CP3 V3.0 firmware V31.1.9.91 contains a stack-based buffer overflow in the RTSP service. The device fails to validate the length of the clock= value in the Range header field when processing a PLAY request. An unauthenticated remote attacker who has completed a standard RTSP session handshake can send a PLAY request with an excessively long clock= value to cause the RTSP service to crash.
AI Analysis
Technical Summary
The vulnerability CVE-2026-51601 affects Tenda CP3 V3.0 firmware version 31.1.9.91. It is a stack-based buffer overflow in the RTSP service triggered by a malformed PLAY request containing an overly long clock= value in the Range header. The device does not properly validate this length, allowing an unauthenticated attacker who has completed the RTSP handshake to crash the RTSP service, causing denial of service. There is no information about available patches or fixes, and no known exploits in the wild have been reported.
Potential Impact
Successful exploitation causes the RTSP service on the affected device to crash, resulting in denial of service. There is no indication of confidentiality or integrity impact. The vulnerability requires no privileges and no user interaction, making it remotely exploitable over the network.
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.
