Attack a Vulnerable App

On this lab we will attack Rails Goat (our vulnerable app).

---

Run Rails Goat

1. Log into your AWS instance and run Rails Goat. This should be a continuation from the previous lab.

$ vagrant ssh
$ export RAILS_ENV=mysql
$ bundle exec rails server -b 0.0.0.0 -p 8080

2. Load http://PUBLIC_IP_ADDRESS:8080 on your browser.

Install Burp

We use Burp Proxy to intercept our browser's requests before they are sent to the Web application. This gives us the chance to modify the HTTP request before it is submitted.

1. Download and run Burp Proxy (Free Edition).

https://portswigger.net/burp/download.html

2. Select Temporary project and click Next. Select Use Burp defaults and click Start Burp.

3. Setup your browser to use the burp proxy.

E.g., on Firefox, Preferences > Advanced > Network > Settings. Select Manual proxy configuration and put localhost and 8080 for HTTP Proxy and Port.

4. Now reload your browser and take a look at Burp > Proxy > Intercept. Here you can modify requests before they are submitted by the browser. Click Forward.
