listening on the remote host is potentially affected by the following
vulnerabilities :

  - An error exists related to LDAP authentication that

  - An error exists related to HTTP authentication, the API
    function 'user.login' call and user switching that could
    allow a security bypass. (CVE-2014-1682)

  - An error exists related to the user type 'Zabbix Admin'
    that could allow unauthorized application changes that
    should be reserved only for the user type 'Zabbix Super
    Admin'. (CVE-2014-1685)

Note that Nessus has not tested for thes issues but has instead relied
only the version in the Zabbix login page.");
