Dockerized DVWA

Damn Vulnerable Web Application (DVWA) is a PHP/MySQL web application that is damn vulnerable. Its main goal is to be an aid for security professionals to test their skills and tools in a legal environment, help web developers better understand the processes of securing web applications and to aid both students & teachers to learn about web application security in a controlled class room environment.

DVWA has an official Docker image available at Dockerhub, however by the time of writing this image did not receive any recent updates.

If you need an always up-to-date version or arm64 images, you can use the here provided Docker Compose setup. The image is built every night against the latest master branch of the DVWA and pushed to Dockehub.

Additionally this Docker image comes with a few CTF challenges that require you to completely compromise the machine and reach root access. Read here for details.

🔧 Configuration

This setup allows you to configure a few settings via the .env file.

Variable	Default	Settings
`PHP_VERSION`	`8.1`	PHP version to run DVWA (`5.6`, `7.0`, `7.1`, `7.2`, `7.3`, `7.4`, `8.0` or `8.1`)
`LISTEN_PORT`	`8000`	Local port for the web server to listen on
`RECAPTCHA_PRIV_KEY`		Required to make the captcha module work. (See FAQ section below)
`RECAPTCHA_PUB_KEY`		Required to make the captcha module work. (See FAQ section below)
`PHP_DISPLAY_ERRORS`	`0`	Set to `1` to display PHP errors (if you want a really easy mode)

The following .env file variables are default settings and their values can also be changed from within the web interface:

Variable	Default	Settings
`SECURITY_LEVEL`	`medium`	Adjust the difficulty level for the challenges^[1] (`low`, `medium`, `high` or `impossible`)
`PHPIDS_ENABLED`	`0`	Set to `1` to enable PHP WAF/IDS^[2] (off by default)
`PHPIDS_VERBOSE`	`0`	Set to `1` to display WAF/IDS reasons for blocked requests

^[1] For the SECURITY_LEVEL changes to take effect, you will have to clear your cookies. Alternatively change it in the web interface.
^[2] WAF (Web Application Firewall) / IDS (Intrusion Detection System)

🏴‍☠️ Capture the flag

Additionally to the default DVWA features, this flavour also contains a few flags that can be captured via various means (including local privilege escalation).

Flag 1: flag{b9bbcb33e11b80be759c4e844862482d}
Flag 2: flag{fc3fd58dcdad9ab23faca6e9a36e581c}
Flag 3: flag{eca7d1f3cf60a8b5344a49287b9076e4}

How to play?

✔️ You must gain access to the running Docker container through the web application.
⛔ You cannot use docker exec -it dvwa_web bash to gain access

Let me know on 🐦 Twitter if you've solved them and how easy/difficult they were.

⚙️ Tools

The DVWA Docker image contains the following tools assisting you in solving the challenges and also allowing you to gain access via reverse shells.

bash
netcat
ping
sudo
telnet
python3

💡 FAQ

Q: I want to proxy through BurpSuite, but it does not work on localhost or 127.0.0.1.

Browsers ususally bypass localhost or 127.0.0.1 for proxy traffic. One solution is to add an alternative hostname to /etc/hosts and access the application through that.

/etc/hosts:

127.0.0.1  dvwa

Then use http://dvwa:8000 in your browser.

Q: How can I run DVWA with a different PHP version?

The here provided Docker images are built against all common PHP versions and you can easily select your version of choice in the .env prior startup. To do so, just uncomment the version of choice and restart the Docker Compose stack:
.env

# PHP VERSION
# -----------
# Uncomment one of the PHP versions you want to use for DVWA
#PHP_VERSION=5.6
#PHP_VERSION=7.0
#PHP_VERSION=7.1
#PHP_VERSION=7.2
#PHP_VERSION=7.3
#PHP_VERSION=7.4
#PHP_VERSION=8.0
PHP_VERSION=8.1

Q: How can I reset the database and start fresh?

The database uses a Docker volume and you can simply remove it via:

# the command below will stop all running container,
# remove their state and delete the MySQL docker volume.
make reset

Q: How can I view Apache access or error log files?

Log files are piped to stderr from the Docker container and you can view them via:

make logs

Q: How can I get a shell on the web server container?

Note: Doing so is basically cheating, you are supposed to gain access to the machine via exploitation.

You can enter the running web server container as root via:

make enter

Q: How do I setup the reCAPTCHA key?

Go to https://www.google.com/recaptcha/admin and generate your captcha as shown below:

Ensure to choose reCAPTCHA v2
Ensure to add all domains you plan on using

Add SITE KEY to the RECAPTCHA_PUB_KEY variable in your .env file
Add SECRET KEY to the RECAPTCHA_PRIV_KEY variable in your .env file

Q: How can I access/view the MySQL database?

Note: Doing so is basically cheating, but if you really need to, you can do so.

This Docker image bundles Adminer (a PHP web interace similar to phpMyAdmin) and you can access it here: http://localhost:8000/adminer.php

Server: dvwa_db
Username: root
Password: rootpass

Q: How can I build the Docker image locally?

To build or rebuild the Docker image against new updates in DVWA master branch, simply do the following:

# This is builing the image for the default PHP version
make rebuild

# This is building the image with PHP 8.0
make rebuild VERSION=8.0

# Rebuild PHP 8.1 for arm64 platform
make rebuild VERSION=8.0 ARCH=linux/arm64
