Summary

  o A vulnerability in the web-based management interface of Cisco DNA Center
    could allow an authenticated, remote attacker to conduct a cross-site
    scripting (XSS) attack against a user of the web-based management interface
    of an affected device.

    The vulnerability is due to insufficient validation of user-supplied input
    by the web-based management interface of an affected device. 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 allow the
    attacker to access sensitive browser-based information.

    There are no workarounds that address this vulnerability.
