Descriptions

A vulnerability in the web-based management interface of the Cisco RV110W Wireless-N VPN Firewall, Cisco RV130W Wireless-N Multifunction VPN Router, and Cisco RV215W Wireless-N VPN Router could allow an unauthenticated, remote attacker to cause a denial of service condition or to execute arbitrary code. The vulnerability is due to improper boundary restrictions on user-supplied input in the Guest user feature of the web-based management interface. An attacker could exploit this vulnerability by sending malicious requests to a targeted device, triggering a buffer overflow condition. A successful exploit could allow the attacker to cause the device to stop responding, resulting in a denial of service condition, or could allow the attacker to execute arbitrary code.

Una vulnerabilidad en la interfaz de gestión web de los dispositivos Cisco RV110W Wireless-N VPN Firewall, Cisco RV130W Wireless-N Multifunction VPN Router y Cisco RV215W Wireless-N VPN Router podría permitir que un atacante remoto no autenticado provoque una denegación de servicio (DoS) o ejecute código arbitrario. La vulnerabilidad se debe a restricciones de límites incorrectas en las entradas proporcionadas en la característica Guest user de la interfaz de gestión web. Un atacante podría explotar esta vulnerabilidad mediante el envío de peticiones maliciosas a un dispositivo objetivo, desencadenando una condición de desbordamiento de búfer. Su explotación con éxito podría permitir que el atacante provoque que el dispositivo deje de responder, resultando en una denegación de servicio (DoS), o podría permitir que el atacante ejecute código arbitrario.
