Descriptions
A vulnerability in the Universal Plug-and-Play (UPnP) service 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 improper validation of incoming UPnP traffic. An attacker could exploit this vulnerability by sending a crafted UPnP request 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 DoS condition. Cisco has not released software updates that address this vulnerability.
Una vulnerabilidad en el servicio Universal Plug-and-Play (UPnP) de los Routers Cisco Small Business RV110W, RV130, RV130W y RV215W, podría permitir a un atacante no autenticado remoto ejecutar código arbitrario o hacer que un dispositivo afectado se reinicie inesperadamente, resultando en una condición de denegación de servicio (DoS). Esta vulnerabilidad es debido a una comprobación inapropiada del tráfico UPnP entrante. Un atacante podría explotar esta vulnerabilidad mediante el envío de una petición UPnP diseñada a 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 DoS. Cisco no ha publicado actualizaciones de software que aborden esta vulnerabilidad.
