Unauthenticated code execution via stbpvid stack overwrite
Published Jan 22, 2026 · Updated Jan 22, 2026
Stack-based buffer overflow in Tenda AX3 firmware 16.03.12.11 allows remote attackers to execute code via an IPTV request. The formGetIptv handler improperly handles the attacker-controlled stbpvid value, allowing it to overwrite the stbpvid stack buffer. No authentication or user interaction is required, and successful exploitation corrupts process memory and permits code execution on the router.
