Damn Vulnerable Web Application (DVWA): The Classic Playground for Web App Security
Welcome to DVWA: Learn Web Security the Hands-On Way
Damn Vulnerable Web Application (DVWA) is a legendary tool in the cybersecurity world, purposefully crafted to be insecure. Built using PHP and MariaDB, DVWA is designed for learning, practicing, and testing web security techniques in a safe and controlled environment.
Whether you’re a budding ethical hacker, a seasoned pentester, or a developer trying to build more secure applications, DVWA offers a rich environment filled with real-world vulnerabilities. It’s perfect for hands-on practice with web security challenges.
Use Cases for DVWA
DVWA is ideal for:
- Practicing common web vulnerabilities like XSS, SQLi, CSRF, and file inclusion
- Testing and developing security tools in a controlled environment
- Teaching web security concepts to students in labs or classrooms
- Running Capture The Flag (CTF) competitions
The app includes both documented and hidden vulnerabilities, encouraging exploration and deep learning.
Installation and Setup
You can install DVWA in various ways based on your environment and comfort level:
1. Manual Installation
Clone the repository and set up the application using Apache, PHP, and MariaDB. You’ll need:
- Apache2
- PHP (v7.3+ recommended)
- MariaDB server and client
- PHP modules like mysqli and gd
On Debian-based systems, install dependencies using:
```
apt update
apt install -y apache2 mariadb-server mariadb-client php php-mysqli php-gd libapache2-mod-php
```
2. Docker
If you prefer containerization, DVWA has an official Docker image. After installing Docker and Docker Compose, simply run:
```
git clone https://github.com/digininja/DVWA.git
cd DVWA
docker compose up -d
```
DVWA will be available at http://localhost:4280.
