"A vulnerability in the web-based management interface of Cisco Identity Services Engine (ISE) could allow an 
unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based 
management 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 malicious 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.
