Synopsis
Drupal 8.9.x < 8.9.10 Remote Code Execution
Description
According to its self-reported version, the instance of Drupal running on the remote web server is 7.0.x prior to 7.75, 8.8.x prior to 8.8.12, 8.9.x prior to 8.9.10 or 9.0.x prior to 9.0.9. It is, therefore, affected by a remote code execution due to the PEAR Archive_Tar library used by Drupal.
Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Update to Drupal version 8.9.10 or latest.
