WebGoat: A deliberately insecure Web Application
Introduction
WebGoat is a deliberately insecure web application maintained by OWASP designed to teach web application security lessons.
This program is a demonstration of common server-side application flaws. The exercises are intended to be used by people to learn about application security and penetration testing techniques.
WARNING 1: While running this program your machine will be extremely vulnerable to attack. You should disconnect from the Internet while using this program. WebGoat’s default configuration binds to localhost to minimize the exposure.
WARNING 2: This program is for educational purposes only. If you attempt these techniques without authorization, you are very likely to get caught. If you are caught engaging in unauthorized hacking, most companies will fire you. Claiming that you were doing security research will not work as that is the first thing that all hackers claim.

Installation instructions:
For more details check the Contribution guide
1. Run using Docker
Already have a browser and ZAP and/or Burp installed on your machine in this case you can run the WebGoat image directly using Docker.
Every release is also published on DockerHub.
|
|
For some lessons you need the container run in the same timezone. For this you can set the TZ environment variable. E.g.
|
|
If you want to use OWASP ZAP or another proxy, you can no longer use 127.0.0.1 or localhost. but you can use custom host entries. For example:
|
|
Then you can run the container with:
|
|
Then visit http://www.webgoat.local:8080/WebGoat/ and http://www.webwolf.local:9090/WebWolf/
2. Run using Docker with complete Linux Desktop
Instead of installing tools locally we have a complete Docker image based on running a desktop in your browser. This way you only have to run a Docker image which will give you the best user experience.

|
For a full overview of all the parameters you can use, please check the [WebGoat properties file](webgoat-container/src/main/resources/application-{webgoat, webwolf}.properties).
4. Run from the sources
Prerequisites:
- Java 23
- Your favorite IDE
- Git, or Git support in your IDE
Open a command shell/window:
|
|
Now let’s start by compiling the project.
|
|
Now we are ready to run the project. WebGoat is using Spring Boot.
|
|
… you should be running WebGoat on http://localhost:8080/WebGoat momentarily.
Note: The above link will redirect you to login page if you are not logged in. LogIn/Create account to proceed.
To change the IP address add the following variable to the WebGoat/webgoat-container/src/main/resources/application.properties file:

4. Run with custom menu
For specialist only. There is a way to set up WebGoat with a personalized menu. You can leave out some menu categories or individual lessons by setting certain environment variables.
For instance running as a jar on a Linux/macOS it will look like this:
|
|
Or in a docker run it would (once this version is pushed into docker hub) look like this:
