Drupal 8.x < 8.3.9 RCE

critical Nessus Network Monitor Plugin ID 700228
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote server is hosting an outdated installation of Drupal that is vulnerable to a critical remote code execution attack vector.

Description

The version of Drupal installed on the remote server is 8.x prior to 8.3.9, and is affected by a flaw in the 'preHandle()' function in 'core/lib/Drupal/Core/DrupalKernel.php' that is triggered as certain parameter keys within HTTP requests are not properly sanitized. This may allow a remote attacker to execute arbitrary code. This issue may be exploited using multiple unspecified attack vectors.

Solution

Upgrade to Drupal 8.3.9 or later.
