Summary
o A vulnerability in the web-based management interface of Cisco Identity
Services Engine (ISE) Software 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 of the
affected device does not properly validate user-supplied input. 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 affected interface or access sensitive,
browser-based information.
Cisco has released software updates that address this vulnerability. There
are no workarounds that address this vulnerability.
