Router crash via security parameter stack overflow
Published Mar 28, 2024 · Updated Aug 2, 2024
Stack-based buffer overflow in Tenda FH1203 firmware 2.0.1.6 allows attackers on the adjacent network to crash the router via Wi-Fi settings. The formWifiBasicSet handler accepts an overlong security parameter that corrupts stack memory; the public disclosure does not identify the exact copy operation or buffer size. No privileges or user interaction are required, but access from the router's adjacent network is necessary, and the documented consequence is service interruption rather than data disclosure or modification.
