First Published: 2021 January 13 16:00 GMT
Version 1.0: Final

Summary
o A vulnerability in the web-based management interface of Cisco DNA Center
software could allow an authenticated, remote attacker to conduct a
cross-site scripting (XSS) attack against a user of the interface of an
affected device.
The vulnerability exists because the web-based management interface does
not properly validate user-supplied input. An attacker could exploit this
vulnerability by persuading a user 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. To
exploit this vulnerability, an attacker would need to have administrative
credentials on the affected device.
There are no workarounds that address this vulnerability.
