Descriptions

A vulnerability in the CLI of Cisco SD-WAN Software could allow an authenticated, local attacker to access sensitive information on an affected device. The vulnerability is due to insufficient input validation of requests that are sent to the iperf tool. An attacker could exploit this vulnerability by sending a crafted request to the iperf tool, which is included in Cisco SD-WAN Software. A successful exploit could allow the attacker to obtain any file from the filesystem of an affected device.

Una vulnerabilidad en la CLI del Software Cisco SD-WAN, podría permitir a un atacante local autenticado acceder a información confidencial en un dispositivo afectado. La vulnerabilidad es debido a una comprobación insuficiente de la entrada de las peticiones que son enviadas hacia la herramienta iperf.
