Technical description

A vulnerability in the REST API of Cisco Data Center Network Manager (DCNM) could allow an unauthenticated, remote attacker to bypass authentication and execute arbitrary actions with administrative privileges on an affected device.

A successful exploit could allow the attacker to perform arbitrary actions through the REST API with administrative privileges.
