CVE-2017-3882
Estado: ModificadaCrítica (9.6)—
A vulnerability in the Universal Plug-and-Play (UPnP) implementation in the Cisco CVR100W Wireless-N VPN Router could allow an unauthenticated, Layer 2-adjacent attacker to execute arbitrary code or cause a denial of service (DoS) condition. The remote code execution could occur with root privileges. The vulnerability is due to incomplete range checks of the UPnP input data, which could result in a buffer overflow. An attacker could exploit this vulnerability by sending a malicious request to the UPnP listening port of the targeted device.
Leer descripción completaMostrar menos
An exploit could allow the attacker to cause the device to reload or potentially execute arbitrary code with root privileges. This vulnerability affects all firmware releases of the Cisco CVR100W Wireless-N VPN Router prior to Firmware Release 1.0.1.22. Cisco Bug IDs: CSCuz72642.

"value": "Una vulnerabilidad en la implementación de Universal plug-and-play (UPnP) en el router CVR100W Wireless-N VPN de Cisco, podría permitir a un atacante de capa 2 no autenticado, ejecutar código arbitrario o causar una condición de denegación de servicio (DoS). La ejecución de código remota podría producirse con privilegios root. La vulnerabilidad es debido a comprobaciones de rango incompletas de los datos de entrada UPnP, lo que podría dar como resultado a un desbordamiento de búfer. Un atacante podría explotar esta vulnerabilidad mediante el envío de una petición maliciosa hacia el puerto de escucha UPnP del dispositivo de destino. Una explotación podría permitir al atacante causar que el dispositivo se recargue o potencialmente ejecutar código arbitrario con privilegios root. Esta vulnerabilidad afecta a todas las versiones de firmware del enrutador CVR100W Wireless-N VPN de Cisco anterior a Versión de Firmware 1.0.1.22. ID de bug de Cisco: CSCuz72642."
