Descriptions

Multiple vulnerabilities in the web-based management interface of Cisco Small Business RV320 and RV325 Series Routers and Cisco Small Business RV016, RV042, and RV082 Routers could allow an authenticated, remote attacker with administrative privileges to execute arbitrary code on an affected device. The vulnerabilities are due to insufficient boundary restrictions on user-supplied input to scripts in the web-based management interface. An attacker with administrative privileges that are sufficient to log in to the web-based management interface could exploit each vulnerability by sending crafted requests that contain overly large values to an affected device, causing a stack overflow. A successful exploit could allow the attacker to cause the device to crash or allow the attacker to execute arbitrary code with root privileges on the underlying operating system.

Múltiples vulnerabilidades en la interfaz de administración basada en web de Routers Cisco Small Business RV320 y RV325 Series y Routers Cisco Small Business RV016, RV042, y RV082, podrían permitir a un atacante remoto autenticado con privilegios administrativos ejecutar código arbitrario sobre un dispositivo afectado. Las vulnerabilidades son debido a restricciones de límite insuficientes en la entrada suministrada por el usuario para scripts en la interfaz de administración basada en web. Un atacante con privilegios administrativos que son suficientes para iniciar sesión en la interfaz de administración basada en web podría explotar cada vulnerabilidad mediante el envío de peticiones diseñadas que contienen valores demasiado grandes hacia un dispositivo afectado, causando un desbordamiento de la pila. Una explotación con éxito podría permitir al atacante causar que el dispositivo se bloquee o permitir al atacante ejecutar código arbitrario con privilegios root en el sistema operativo subyacente
