Unauthenticated service interruption via stack buffer overflow
Published Dec 20, 2022 · Updated Apr 17, 2025
Buffer overflow in Tenda i22 1.0.0.3(4687) allows remote attackers to interrupt the HTTP service via a crafted setcfm request. The formSetCfm handler passes attacker-controlled funcpara1 data to sprintf for a 64-byte stack buffer without enforcing its length. No authentication or user interaction is required, and the published proof of concept establishes denial of service rather than code execution.
