CVE-2018-7600Drupalgeddon2 — Unauthenticated Remote Code Execution

Drupal renders parts of a request through its form system without cleaning them first, so an unauthenticated visitor runs code on the site with a single crafted request.

YOUR NEXT MOVE

Upgrade Drupal to 7.58, 8.3.9, 8.4.6 or 8.5.1, and treat any site that ran unpatched while reachable as compromised.
