These vulnerabilities are due to improper validation of user-supplied input in the web-based management interface. An attacker could exploit these vulnerabilities by sending crafted HTTP requests to an affected device. A successful exploit could allow the attacker to execute arbitrary code as the root user on the underlying operating system or cause the device to reload, resulting in a denial of service (DoS) condition. To exploit these vulnerabilities, an attacker would need to have valid administrator credentials on the affected device."},{"lang":"es","value":"Múltiples vulnerabilidades en la interfaz de administración basada en web de los Enrutadores Cisco Small Business RV016, RV042, RV042G, RV082, RV320 y RV325, podrían permitir a un atacante autenticado remoto ejecutar código arbitrario o causar que un dispositivo afectado se reinicie inesperadamente. Estas vulnerabilidades son debido a una comprobación inapropiada de la entrada suministrada por el usuario en la interfaz de administración basada en web. Un atacante podría explotar estas vulnerabilidades mediante el envío de peticiones HTTP diseñadas hacia un dispositivo afectado. Una explotación con éxito podría permitir al atacante ejecutar código arbitrario como usuario root en el sistema operativo subyacente o causar que el dispositivo se recargue, resultando en una condición de denegación de servicio (DoS). Para explotar estas vulnerabilidades, un atacante necesitaría tener credenciales de administrador válidas en el dispositivo
