Remote compromise via NatStaticSetting stack overflow
Published Aug 30, 2023 · Updated Oct 1, 2024
Stack overflow in Tenda AC7, AC9, and AC5 firmware allows remote attackers to execute code via the /goform/NatStaticSetting page parameter. The handler copies attacker-controlled page data into a fixed-size stack buffer without bounds checking, producing an out-of-bounds write. Exploitation requires network access to the router management interface and no authentication according to the published vector; successful exploitation can compromise confidentiality, integrity, and availability.
