Drupal 7.x < 7.43 Multiple Vulnerabilities

Synopsis

The PHP application running on the remote web server is affected by multiple vulnerabilities.

Description

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.

Solution

Upgrade to Drupal version 7.43 or later.
