"The remote web server is running a version of Drupal that is 6.x prior
to 6.32 or 7.x prior to 7.29. It is, therefore, potentially affected
by the following vulnerabilities :

  - The HTTP Host header, which determines the configuration
    file used by Drupal core's multisite feature, does not
    properly validate header values, which may result in a
    denial of service. This may also affect sites that do
    not use the multisite feature. (CVE-2014-5019)

  - The File module in Drupal 7.x does not properly check
    file permissions when creating attachments. This may
    allow attackers to gain access to arbitrary files.
    (CVE-2014-5020)

  - The form API does not properly sanitize option group
    labels in select elements, which may allow unspecified
    cross-site scripting attacks. (CVE-2014-5021)

  - Forms containing a combination of an Ajax-enabled text
    field and a file field may contain an unspecified
    cross-site scripting vulnerability. (CVE-2014-5022)

Note that Nessus has not tested for these issues but has instead
relied only on the application's self-reported version number.");
