CVE-2026-51601: n/a
Tenda CP3 V3.0 firmware version 31.1.9.91 contains a stack-based buffer overflow vulnerability in its RTSP service. The flaw occurs because the device does not properly validate the length of the clock= value in the Range header of a PLAY request. An unauthenticated remote attacker who has completed a standard RTSP session handshake can exploit this by sending a specially crafted PLAY request with an excessively long clock= value, causing the RTSP service to crash.
AI Analysis
Technical Summary
The vulnerability in Tenda CP3 V3.0 firmware 31.1.9.91 is a stack-based buffer overflow in the RTSP service triggered by improper validation of the clock= parameter length in the Range header of a PLAY request. This allows an unauthenticated remote attacker, after completing an RTSP handshake, to send a malicious PLAY request that crashes the RTSP service by overflowing the stack buffer.
Potential Impact
Successful exploitation results in a denial of service condition by crashing the RTSP service on the affected device. There is no information about code execution or data leakage. The attacker does not require authentication but must complete a standard RTSP session handshake first.
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.
