Authenticated memory corruption via unbounded schedule input
Published Mar 29, 2024 · Updated Aug 27, 2024
Stack-based buffer overflow in Tenda FH1205 2.0.0.7(775) allows remote authenticated users to corrupt memory via Wi-Fi schedule input. The setSchedWifi handler fails to bound schedEndTime before it reaches a stack buffer, allowing oversized input to overwrite adjacent memory. Access requires low privileges from an adjacent network, and exploitation can crash the router or corrupt its control flow.
