Drupal 8.x < 8.3.9 RCE

Critical Nessus Network Monitor Plugin ID 700228

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The remote server is hosting an outdated installation of Drupal that is vulnerable to a critical remote code execution attack vector.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