Descriptions

A vulnerability in the web-based management interface of Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers could allow an unauthenticated, remote attacker to execute arbitrary code or cause an affected device to restart unexpectedly, resulting in a denial of service (DoS) condition. This vulnerability is due to insufficient user input validation of incoming HTTP packets. An attacker could exploit this vulnerability by sending a crafted request to the web-based management interface. A successful exploit could allow the attacker to execute arbitrary commands on an affected device using root-level privileges. Cisco has not released software updates that address this vulnerability.

Una vulnerabilidad en la interfaz de administración basada en la web de los routers Cisco Small Business RV110W, RV130, RV130W y RV215W podría permitir a un atacante remoto no autenticado ejecutar código arbitrario o causar el reinicio inesperado del dispositivo afectado, resultando en una condición de denegación de servicio (DoS). Esta vulnerabilidad es debido a una comprobación insuficiente de la entrada del usuario en los paquetes HTTP entrantes. Un atacante podría explotar esta vulnerabilidad mediante el envío de una petición diseñada a la interfaz de administración basada en la web. Una explotación con éxito podría permitir al atacante ejecutar comandos arbitrarios en un dispositivo afectado usando privilegios de nivel root. Cisco no ha publicado actualizaciones de software que aborden esta vulnerabilidad
