"According to its self-reported version, Cisco Data Center Network Manager is prior to version 11.3(1) and is,
therefore, affected by a cross-site scripting vulnerability in the web-based management interface due to insufficient
validation of user-supplied input. An attacker could exploit this vulnerability by persuading a user of the interface
to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context
of the interface or access sensitive, browser-based information. Please see the included Cisco BID and Cisco Security
Advisory for more information.");
