Descriptions
A vulnerability in the Constrained Application Protocol (CoAP) implementation of Cisco IoT Field Network Director could allow an unauthenticated remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to insufficient input validation of incoming CoAP traffic. An attacker could exploit this vulnerability by sending a malformed CoAP packet to an affected device. A successful exploit could allow the attacker to force the CoAP server to stop, interrupting communication to the IoT endpoints.
Una vulnerabilidad en la implementación de Constrained Application Protocol (CoAP) de Cisco IoT Field Network Director podría permitir a un atacante remoto no autenticado causar una condición de denegación de servicio (DoS) sobre un dispositivo afectado. La vulnerabilidad es debido a una comprobación de entrada insuficiente del tráfico CoAP entrante. Un atacante podría explotar esta vulnerabilidad mediante el envío de un paquete CoAP malformado hacia un dispositivo afectado. Una explotación con éxito podría permitir al atacante forzar al servidor de CoAP a detenerse, interrumpiendo la comunicación con los endpoints de IoT.
