"According to its self-reported version, Cisco Identity Services Engine
Software is affected by a cross site scripting vulnerability. 
A vulnerability in the web-based guest portal of Cisco Identity
Services Engine (ISE) could allow an authenticated, remote attacker to
conduct a cross-site scripting (XSS) attack against a user of the
web-based management interface.The vulnerability is due to
insufficient validation of user-supplied input that is processed by
the web-based interface. An attacker could exploit this vulnerability
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 interface or access sensitive
browser-based information.

Please see the included Cisco BIDs and Cisco Security Advisory for
