Multiple vulnerabilities in the web-based management interface of Cisco DNA Center software could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface of an affected device.
The vulnerabilities exist because the web-based management interface on an affected device does not properly validate user-supplied input. An attacker could exploit these vulnerabilities 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 affected interface or access sensitive, browser-based information.
There are no workarounds that address these vulnerabilities.
