Summary
*
A vulnerability in the web UI of Cisco TelePresence Server Software could
allow an unauthenticated, remote attacker to conduct a cross-frame
scripting (XFS) attack against a user of the web UI of the affected
software.
The vulnerability is due to insufficient protections for HTML inline
frames (iframes) by the web UI of the affected software. An attacker could
exploit this vulnerability by persuading a user of the affected UI to
navigate to an attacker-controlled web page that contains a malicious HTML
iframe. A successful exploit could allow the attacker to conduct
click-jacking or other client-side browser attacks on the affected system.
There are no workarounds that address this vulnerability.
