Service interruption via unbounded index parameter
Published Nov 30, 2023 · Updated Aug 2, 2024
Stack buffer overflow in Tenda i6 1.0.0.8(3856) allows remote attackers to interrupt router service through a crafted wifiSSIDget request. The /goform/wifiSSIDget handler passes the unbounded index parameter to sprintf, overflowing a stack buffer. The HTTP endpoint accepts the request without authentication; the published proof of concept demonstrates a denial-of-service path but not code execution.
