CVE-2026-8697

Due to improper enforcement of authentication rate-limiting on a debug SSH service in Archer C64 v1, the SSH service allows unlimited authentication attempts and uses the same credentials as the web interface. This enables an attacker to brute-force valid credentials via SSH. Successful exploitation could allow an attacker with adjacent network access to obtain administrative credentials through unrestricted authentication attempts and subsequently gain full administrative access to the device, impacting system confidentiality, integrity, and availability.

Summary		(es) Debido a una aplicación incorrecta de la limitación de velocidad de autenticación en un servicio SSH de depuración en Archer C64 v1, el servicio SSH permite intentos de autenticación ilimitados y utiliza las mismas credenciales que la interfaz web. Esto permite a un atacante forzar por fuerza bruta credenciales válidas a través de SSH. Una explotación exitosa podría permitir a un atacante con acceso a la red adyacente obtener credenciales administrativas a través de intentos de autenticación sin restricciones y posteriormente obtener acceso administrativo completo al dispositivo, impactando la confidencialidad, integridad y disponibilidad del sistema.
