Summary
A vulnerability in the HTTP web-based management interface of Cisco Unified
Computing System (UCS) Central Software could allow an unauthenticated, remote
attacker to conduct a cross-site scripting (XSS) attack against a user of the
web interface of the affected system.
The vulnerability is due to insufficient input validation of a user-supplied
value. An attacker could exploit this vulnerability by convincing a user to
click a specific link. A successful exploit could allow the attacker to submit
arbitrary requests to the affected system via a web browser with the
privileges of the user.
Cisco has released software updates that address this vulnerability.
Workarounds that address this vulnerability are not available.
