Router compromise via firewall parameter stack overflow
Published Aug 30, 2023 · Updated Oct 1, 2024
Stack overflow in Tenda AC9 3.0 firmware 15.03.06.42_multi allows remote attackers to corrupt memory through a firewall setting request. The /goform/SetFirewallCfg handler accepts oversized firewallEn data and writes beyond a stack buffer without enforcing its length. No authentication or user interaction is required; successful exploitation can crash the router or compromise the firmware process.
