Summary
o A vulnerability in the web-based guest portal of Cisco Identity Services
Engine (ISE) could allow an unauthenticated, remote attacker to conduct a

The vulnerability is due to insufficient validation of user-supplied input
that is processed by the web-based management interface. 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.
