CVE-2021-34739

A vulnerability in the web-based management interface of multiple Cisco Small Business Series Switches could allow an unauthenticated, remote attacker to replay valid user session credentials and gain unauthorized access to the web-based management interface of an affected device. This vulnerability is due to insufficient expiration of session credentials. An attacker could exploit this vulnerability by conducting a man-in-the-middle attack against an affected device to intercept valid session credentials and then replaying the intercepted credentials toward the same device at a later time. A successful exploit could allow the attacker to access the web-based management interface with administrator privileges.

Una vulnerabilidad en la interfaz de administración basada en web de varios switches Cisco Small Business Series podría permitir a un atacante remoto no autenticado reproducir credenciales de sesión de usuario válidas y conseguir acceso no autorizado a la interfaz de administración basada en web de un dispositivo afectado. Esta vulnerabilidad es debido a una caducidad insuficiente de las credenciales de sesión. Un atacante podría explotar esta vulnerabilidad llevando a cabo un ataque de tipo man-in-the-middle contra un dispositivo afectado para interceptar las credenciales de sesión válidas y luego reproducir las credenciales interceptadas hacia el mismo dispositivo en un momento posterior. Una explotación con éxito podría permitir al atacante acceder a la interfaz de administración basada en la web con privilegios de administrador
