Published Mar 29, 2024 · Updated Aug 19, 2024

Stack overflow in Tenda FH1205 2.0.0.7(775) allows remote authenticated users on an adjacent network to crash its web service. The fromDhcpListClient handler accepts an oversized list1 parameter without enforcing the destination stack buffer bounds. Access to the authenticated management interface from an adjacent network is required; successful exploitation interrupts availability.
