"According to its self-reported version, Cisco Data Center Network Manager is prior to version 11.0(1) and is,
therefore, affected by a privilege escalation vulnerability in the web-based management interface due to incomplete
validation of user input. An authenticated attacker could exploit this vulnerability by sending a crafted HTTP
request to the target application in order to issue commands on the underlying operating system as the root user.

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