The System module in Drupal 6.x before 6.38 and 7.x before 7.43 might allow remote attackers to hijack the authentication of site administrators for requests that download and run files with arbitrary JSON-encoded content, aka a "reflected file download vulnerability."

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - The System module in Drupal 6.x before 6.38 and 7.x before 7.43 might allow remote attackers to hijack the     authentication of site administrators for requests that download and run files with arbitrary JSON-encoded     content, aka a reflected file download vulnerability. (CVE-2016-3168)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of Drupal running on the remote web server is 7.x prior to 7.43. It is, therefore, affected by the following vulnerabilities :

  - A flaw exists in the File module that allows an attacker     to view, delete, or substitute a link to a file that has     not yet been submitted or processed by a form. An     authenticated, remote attacker can exploit this, via     continuous deletion of temporary files, to block all     file uploads to a site.

  - A flaw exists in the XML-RPC system due to a failure to     limit the number of simultaneous calls being made to the     same method. A remote attacker can exploit this to     facilitate brute-force attacks.

  - A cross-site redirection vulnerability exists due to     improper validation of unspecified input before     returning it to the user, which can allow the current     path to be filled-in with an external URL. A remote     attacker can exploit this, via a crafted link, to     redirect a user to a malicious web page of the     attacker's choosing that targets weaknesses in the     client-side software or is used for phishing attacks.

  - An unspecified reflected file download flaw exists that     allows an attacker to trick a user into downloading and     running a file with arbitrary JSON-encoded content.

  - A flaw exists, related to how the user_save() API is     utilized, due to assigning improper roles when saving     user accounts. An authenticated, remote attacker can     exploit this, via crafted data added to a form or array,     to gain elevated privileges.

  - An information disclosure vulnerability exists in the     'have you forgotten your password' due to displaying the     username when a valid email address is provided. A     remote attacker can exploit this to obtain the usernames     recognized by the system.

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