A vulnerability in the DNS functionality of Cisco Nexus Dashboard Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition.

This vulnerability is due to the improper processing of DNS requests. An attacker could exploit this vulnerability by sending a continuous stream of DNS requests to an affected device. A successful exploit could allow the attacker to cause the coredns service to stop working or cause the device to reload, resulting in a DoS condition.
