Code execution via unchecked domain parameter
Published Feb 22, 2024 · Updated Aug 28, 2024
Stack-based buffer overflow in Tenda AC9 V3 firmware 15.03.06.42_multi allows remote attackers to execute arbitrary code over the local network. The add_white_node handler places the attacker-controlled domain parameter into a stack buffer without checking its length, allowing crafted data to overwrite adjacent stack state. No authentication or user interaction is required, but the attacker must have adjacent-network access; exploitation can also crash the router.
