Summary
o A vulnerability in the web-based management interface of Cisco Digital
Network Architecture (DNA) Center could allow an authenticated, remote
attacker to conduct a stored 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 to click a crafted
link. A successful exploit could allow the attacker to execute arbitrary
script code in the context of the affected interface or access sensitive,
browser-based information. To exploit this vulnerability, the attacker
needs administrator credentials.
