Descriptions

Multiple vulnerabilities in the web-based management interface of Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers could allow an authenticated, remote attacker to execute arbitrary code on an affected device or cause the device to restart unexpectedly, resulting in a denial of service (DoS) condition. These vulnerabilities are due to insufficient validation of user fields within incoming HTTP packets. An attacker could exploit these vulnerabilities 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 with root-level privileges or to cause the device to restart unexpectedly, resulting in a DoS condition. To exploit these vulnerabilities, an attacker would need to have valid Administrator credentials on the affected device. Cisco has not released software updates that address these vulnerabilities.

Múltiples vulnerabilidades en la interfaz de administración basada en web de los routers Cisco Small Business versiones RV110W, RV130, RV130W y RV215W, podrían permitir a un atacante autenticado y remoto ejecutar código arbitrario en un dispositivo afectado o causar el reinicio inesperado del dispositivo, resultando en una condición de denegación de servicio (DoS). Estas vulnerabilidades son debido a que no son comprobados suficientemente los campos de usuario en los paquetes HTTP entrantes. Un atacante podría explotar estas vulnerabilidades mediante el envío de una petición diseñada a la interfaz de administración basada en web. Una explotación con éxito podría permitir al atacante ejecutar comandos arbitrarios en un dispositivo afectado con privilegios de nivel root o causar que el dispositivo sea reiniciado inesperadamente, resultando en una condición de DoS. Para explotar estas vulnerabilidades, un atacante necesitaría tener credenciales de administrador válidas en el dispositivo afectado. Cisco no ha publicado actualizaciones de software que aborden estas vulnerabilidades
