Summary

  o A vulnerability in the web-based management interface of the Cisco
    Registered Envelope Service could allow an authenticated, remote attacker
    to conduct a cross-site scripting (XSS) attack against a user of the
    web-based management interface of the affected service.

    The vulnerability is due to insufficient validation of user-supplied input
    that is processed by the web-based management interface of the affected
    service. An attacker could exploit this vulnerability by persuading a user
    of the interface to click a malicious link. A successful exploit could
    allow the attacker to execute arbitrary script code in the context of the
    interface or access sensitive browser-based information.

    There are no workarounds that address this vulnerability.
