Unauthenticated memory corruption via unbounded conType copy
Published Sep 16, 2022 · Updated Aug 3, 2024
Buffer overflow in Tenda RX9 Pro 22.03.02.10 allows remote attackers to corrupt memory through a crafted setIPv6Status request. The httpd setIPv6Status handler copies the attacker-controlled conType form value with strcpy into a fixed-size destination without a length check. No authentication or user interaction is required, and the published proof of concept does not establish a specific post-corruption outcome.
