Descriptions

A vulnerability in the integrated wireless access point (AP) packet processing of the Cisco 1000 Series Connected Grid Router (CGR1K) could allow an unauthenticated, adjacent attacker to cause a denial of service condition on an affected device. This vulnerability is due to insufficient input validation of received traffic. An attacker could exploit this vulnerability by sending crafted traffic to an affected device. A successful exploit could allow the attacker to cause the integrated AP to stop processing traffic, resulting in a DoS condition. It may be necessary to manually reload the CGR1K to restore AP operation.

Una vulnerabilidad en el procesamiento de paquetes del punto de acceso inalámbrico (AP) integrado del router de red conectada de Cisco 1000 Series Connected Grid Router (CGR1K) podría permitir a un atacante adyacente no autenticado causar una condición de denegación de servicio en un dispositivo afectado. Esta vulnerabilidad es debido a que no ha sido suficientemente la entrada del tráfico recibido. Un atacante podría aprovechar esta vulnerabilidad mediante el envío de tráfico diseñado a un dispositivo afectado. Una explotación con éxito podría permitir al atacante causar que el AP integrado deje de procesar el tráfico, resultando en una condición de DoS. Puede ser necesario recargar manualmente el CGR1K para restaurar el funcionamiento del AP
