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.
