Security scans of 2018.1 and earlier may show the following vulnerabilities reported in Drupal:
CVE-2019-6338 - Drupal is prone to a remote PHP object-injection vulnerability.
CVE-2019-6339 - Drupal is prone to a remote code-execution vulnerability.
Release : 2018.1
Drupal was used by 2018.1 and earlier to serve product documentation for offline usage.
2018.1 is end of life and no longer supported. The recommendation is to update to the newest version of on-premise which no longer uses Drupal
If upgrading is not possible, the workaround is to delete the directory or set permissions to deny access to all users:
# chmod 000 /var/www/html/help
# rm -rf /var/www/html/help
