Memory corruption via sprintf buffer overflow
Published Sep 7, 2022 · Updated Jun 17, 2025
Buffer overflow in the httpd binary in Tenda G3 firmware 15.11.0.6(7663) allows remote attackers to corrupt memory via network requests. The public record attributes the overflow to sprintf but does not identify the function, destination buffer, or attacker-controlled input. Network access requires no authentication or user interaction; the record does not distinguish a service crash from other memory-corruption consequences.
