According to its self-reported version, Cisco Data Center Network Manager is affected by an authentication bypass vulnerability in the REST API due to insufficient authorization of certain API functions. An attacker can exploit this vulnerability by sending a crafted request to the API using low-privileged credentials in order to perform arbitrary actions through the REST API with administrative privileges.

Please see the included Cisco BID and Cisco Security Advisory for more information.
