"The remote web server is running a version of Drupal that is 7.x prior
to 7.39. It is, therefore, potentially affected by the following
vulnerabilities :

  - A cross-site scripting vulnerability exists in the
    autocomplete functionality due to improper validation of
    input passed via requested URLs. An authenticated,
    remote attacker can exploit this, via a specially
    crafted request, to execute arbitrary script code.
    (CVE-2015-6658)

  - A SQL injection vulnerability exists in the SQL comment
    filtering system due to improper sanitization of
    user-supplied input before using it in SQL queries. An
    authenticated, remote attacker can exploit this to
    inject SQL queries, resulting in the manipulation or
    disclosure of arbitrary data. (CVE-2015-6659)

  - A cross-site request forgery vulnerability exists in the
    form API due to improper validation of form tokens. An
    authenticated, remote attacker can exploit this, via a
    specially crafted link, to upload arbitrary files under
    another user's account. (CVE-2015-6660)

  - An information disclosure vulnerability exists that
    allows a remote, authenticated user to view the titles
    of nodes that they do not have access to.
    (CVE-2015-6661)

  - A cross-site scripting vulnerability exists due to
    improper validation of user-supplied input when invoking
    Drupal.ajax() on whitelisted HTML elements. A remote
    attacker can exploit this, via a specially crafted
    request, to execute arbitrary script code.
    (CVE-2015-6665)

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