Authenticated code execution via speed_dir stack overflow
Published Mar 27, 2024 · Updated Aug 12, 2024
Stack-based buffer overflow in Tenda FH1202 1.2.0.14(408) allows remote authenticated users to execute code via speed_dir. The formSetSpeedWan handler for /goform/SetSpeedWan places an oversized speed_dir value in a fixed-size stack buffer without validating its length. Access to the network management interface is required; successful exploitation can crash the router service or run code with the handler's privileges.
