For the lab assignments we use WebGoat 5.4 and WebScarab.

Installation instructions

Warning: de Tomcat server in WebGoat does not seem to work on Java 8, so use Java 7 instead.

using your own laptop or PC:
follow the instructions of our manual of WebGoat and WebScarab on how to install and use the tools.
in HG00.075 and other faculty terminal rooms:
WebGoat are WebScarab in the xpcursus drive, which is automatically mounted if you start Windows 7.
Go to Start > Computer and then to xpcursus (T:) > SWS2014
There you will find a README.txt with the instructions below:
- Copy the directories WebGoat-5.4 and WebScarab to the local D: disk (not to the Desktop)
- To run WebGoat: open D:\WebGoat-5.4\webgoat_8080
- To run WebScarab: open WebScarab\webscarab
Use the browser Chrome or Firefox with these tools, Internet Explorer 8 will not work.
For instructions on how to configure your browser and WebScarab, see our manual of WebGoat and WebScarab: (on page 4 and 7; you can skip all the other installation instructions).

There is lots of additional info on installation and use at the WebGoat 5.4 and WebScarab websites, but you shouldn't need that.

Starting everything up after the installation

To keep an overview with all the tools and installation instructions above: once everything is installed, you have to

start Webgoat,
start WebScarab,
start your browser - Firefox or Chrome, and
1. configure the network connection settings to use localhost port 8008 as a proxy,
2. surf to http://localhost:8080/WebGoat/attack - NB port 8080, not port 8008, and login as guest with password guest.

and you should be ready to start on the exercises below.

Assignments

Below the WebGoat exercises that we will do, per category. You can simply start from the top; precisely which ones should be handed in by when will be announced as we go along. You should at least be able to get 1, 2, and 3 done in the first werkcollege, unless you run into serious installation difficulties.

The WebGoat maintains a score card, which shows which lessons you have done, and how many hints you used.
When you are done with an lesson, print this report card to a PDF file (because when you restart webgoat in a VM or terminal room this information might be lost).
Give this file a meaningful name, which should include the number of the lesson, the date and your names. We will sent email announcements on how and when you to hand in these report cards, via Blackboard assignments, so that we can find out which lessons typically requires more/fewer hints. (The number of hints you needed won't count towards a grade or anything, so there is no reason to cheat. Clearly, the whole report card can be faked anyway.) We changed the order but kept the original numbering, so the numbering below is not always consecutive.
