Summary
A vulnerability in the web-based management interface of Cisco UCS Director
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 is due to insufficient validation of user-supplied input
by the web-based management interface of an affected device. 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 allow the
attacker to access sensitive browser-based information.
There are no workarounds that address this vulnerability.
