Drupal 6.x < 6.38 Multiple Vulnerabilities

high Nessus Network Monitor Plugin ID 9216

Synopsis

The remote server is hosting an outdated installation of Drupal that is vulnerable to multiple attack vectors.

Description

The remote server is hosting an outdated version of Drupal, a PHP-based open-source content management system. The version of Drupal installed on the remote server is 6.x prior to 6.38, and is affected by the following vulnerabilities :

- A flaw exists in the deserialization of user-supplied session data. An authenticated, remote attacker can exploit this, via truncated session data, to execute arbitrary code.
- 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.
- A flaw exists that allows input, such as JavaScript, to be submitted for form buttons even if '#access' is set to FALSE in the server-side form definition. An authenticated, remote attacker can exploit this to bypass access restrictions.
- A flaw exists in the 'drupal_set_header()' function due to improper sanitization of user-supplied input passed as the header value. A remote attacker can exploit this, via crafted content containing line breaks, to set arbitrary headers.
- A flaw exists in the 'drupal_goto()' function due to a failure to properly validate the content of the '$_REQUEST['destination']' value before returning it to the user. 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.

Solution

Upgrade to Drupal 6.38, or later.
