Summary

  o A vulnerability in the web-based management interface of Cisco Unified
    Communications Manager could allow an authenticated, remote attacker to
    view digest credentials in clear text.

    The vulnerability is due to the incorrect inclusion of saved passwords in
    configuration pages. An attacker could exploit this vulnerability by
    logging in to the Cisco Unified Communications Manager web-based management
    interface and viewing the source code for the configuration page. A
    successful exploit could allow the attacker to recover passwords and expose
    those accounts to further attack.

    There are no workarounds that address this vulnerability.
