"According to its self-reported version, Cisco Identity Services Engine
Software is affected by a cross-site scripting vulnerability.
This 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.
