Denial of service via formSetAutoPing overflow
Published Sep 23, 2022 · Updated May 22, 2025
Buffer overflow in Tenda i9 1.0.0.8(3828) allows attackers to cause denial of service through a crafted string. The formSetAutoPing handler processes attacker-controlled string data without sufficient bounds checking, overflowing its buffer. Triggering the flaw interrupts router service; available records do not establish authentication or network preconditions.
