"According to its self-reported version, Cisco Data Center Network Manager is prior to version 11.3(1) and is,
therefore, affected by a privilege escalation vulnerability in the REST API endpoint due to insufficient access control
validation. An authenticated, remote attacker could exploit this vulnerability by authenticating with a low-privilege
account and sending a crafted request to the API. A successful exploit could allow the attacker to interact with the
API with administrative privileges. Please see the included Cisco BID and Cisco Security Advisory for more information.");
