Multiple vulnerabilities in the web-based user interfacenbsp;(web UI) of Cisconbsp;IOS XE Software could allow an unauthenticated, remote attacker to conduct a cross-site scriptingnbsp;(XSS) attack against a user of the web UI of the affected software.

The vulnerabilities are due to insufficient input validation of certain parameters that are passed to the affected software via the web UI.

An attacker could exploit these vulnerabilities by persuading a user of the affected UI to access a malicious link or by intercepting a user request for the affected UI and injecting malicious code into the request.

A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected UI or allow the attacker to access sensitive browser-based information on the userrsquo;s system.
There are no workarounds that address these vulnerabilities.
