What is CVE-2017-6780?

A vulnerability in the TCP throttling process of Cisco's IoT Field Network Director allows unauthenticated remote attackers to send a high volume of TCP packets to specific listening ports, leading to memory exhaustion. This can result in the targeted system consuming excessive memory, ultimately forcing it to restart, which creates a temporary denial of service condition. The vulnerability is primarily a result of insufficient rate-limiting protection and affects specific releases of the Connected Grid Network Management System and IoT Field Network Director.
