Drupal 7.x < 7.74 / 8.x < 8.8.11 / 8.9.x < 8.9.9 / 9.0.x < 9.0.8 RCE (SA-CORE-2020-012)

high Nessus Plugin ID 143126

Synopsis

A PHP application running on the remote web server is affected by a remote code execution vulnerability.

Description

According to its self-reported version, the instance of Drupal running on the remote web server is 7.x prior to 7.74, 8.x prior to 8.8.11, 8.9.x prior to 8.9.9, or 9.0.x prior to 9.0.8. It is, therefore, affected by a remote code execution vulnerability in its file upload functionality due to a failure to sanitize filenames. An authenticated, remote attacker can exploit this to execute arbitrary php code under certain hosting configurations.

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

Solution

Upgrade to Drupal version 7.74 / 8.8.11 / 8.9.9 / 9.0.8 or later.
