The vulnerability exists because HTTP requests are not properly validated. An attacker could exploit this vulnerability by sending a crafted HTTP request over an SSL connection to an affected device. A successful exploit could allow the attacker to remotely execute arbitrary code on the device or cause the device to reload, resulting in a DoS condition."},{"lang":"es","value":"Una vulnerabilidad en la funcionalidad Secure Sockets Layer (SSL) VPN de Cisco Small Business RV340, RV340W, RV345, y RV345P Dual WAN Gigabit VPN Routers, podría permitir a un atacante remoto no autenticado ejecutar código arbitrario en un dispositivo afectado o causar la recarga del dispositivo, resultando en una condición de denegación de servicio (DoS). La vulnerabilidad se presenta porque las peticiones HTTP no son comprobadas apropiadamente. Un atacante podría explotar esta vulnerabilidad mediante el envío de una petición HTTP diseñada por medio de una conexión SSL hacia un dispositivo afectado.
