**********
Thank you for downloading WebGoat!
This program is a demonstration of common server-side
application flaws. The exercises are intended to
be used by people to learn about application penetration
testing techniques.
WARNING 1: While running this program your machine will be
extremely vulnerable to attack. You should to disconnect
from the Internet while using this program.
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.
You can find more information about WebGoat at:
http://code.google.com/p/webgoat
----------------------------------------------------------------------------------------
Prerequisites for Developers (Skip to Option 3 for unzip and click to run configruation)
----------------------------------------------------------------------------------------
These tools must be installed independent of the webgoat download.
- Java 1.6
Java can ne downloaded at http://java.sun.com/javase/downloads/index.jsp
You only need to download and install the "Java SE Development Kit (JDK)"
- Maven > 2.0.9
Maven can be downloaded at: http://maven.apache.org/
In Ubuntu it can be installed with:
> apt-get install maven2
- WebGoat source code
WebGoat source code can be downloaded at:
http://code.google.com/p/webgoat/source/checkout
Use an svn client (ex: Tortoise svn) to checkout the code in the trunk.
---------------------------------
Building the project (Developers)
---------------------------------
Using a command shell/window:
> cd webgoat
> mvn compile
copy it to the local repository
> mvn install
delete artifacts from previous build:
> mvn clean
-----------------------------------------------
Building the Eclipse project files (Developers)
-----------------------------------------------
> mvn eclipse:clean
> mvn eclipse:eclipse
Afterward the project can be imported within Eclipse:
File -> Import -> General -> Existing Projects into Workspace
and select the webgoat directory as the "root directory." A webgoat should appear in the Projects section of your dialogue window.
Don't forget to declare a classpath variable named M2_REPO, pointing to ~/.m2/repository, otherwise many links to existing jars will be broken.
This folder is located in your username root folder, the same folder where "my documents" and "my pictures" are located.
You can declare new variables in Eclipse in Windows -> Preferences... and selecting Java -> Build Path -> Classpath Variables
-------------------------------------------------------------------
Option 1: (Developers) Run the project on Tomcat within Eclipse
-------------------------------------------------------------------
Install a local Tomcat server (We use Tomcat 7)
1. Download and unzip Apache Tomcat from http://tomcat.apache.org.
2. Adapt the conf/tomcat-users.xml file of your Tomcat server:
<?xml version="1.0" encoding="UTF-8"?>
<tomcat-users>
<role rolename="webgoat_basic"/>
<role rolename="webgoat_admin"/>
<role rolename="webgoat_user"/>
<role rolename="tomcat"/>
<user password="webgoat" roles="webgoat_admin" username="webgoat"/>
<user password="basic" roles="webgoat_user,webgoat_basic" username="basic"/>
<user password="tomcat" roles="tomcat" username="tomcat"/>
<user password="guest" roles="webgoat_user" username="guest"/>
</tomcat-users>
3. Open Eclipse (WTP version) -> File -> New -> Other -> Server -> Apache
4. Choose your Tomcat version
-> Click next "browse" to your tomcat install.
-> Make sure the "JRE" dropdown is pointing to your jdk. If it isn't listed, press
"Installed JREs" and add it.
-> Click next and add "webgoat" to the list of configured applications
-> Finish
3. Right Click on the webgoat project within eclipse -> Run As -> Run on server
Point your browser to http://localhost:8080/webgoat/attack
** Note - When running in eclipse, the default url will be lowercase "webgoat"
-----------------------------------------------------------
Option 2: (Developers) Run the project on Tomcat with Maven
-----------------------------------------------------------
1. mvn tomcat:run-war
2. http://localhost:8080/WebGoat/attack
------------------------------------------------------------------
Option 3: Run from the WebGoat 5.X Standard distribution (Windows)

<!-- A "project" describes a set of targets that may be requested
when Ant is executed. The "default" attribute defines the
target which is executed if no specific target is requested,
and the "basedir" attribute defines the current working directory
from which Ant executes the requested task. This is normally
set to the current working directory.
-->

Each of the following properties are used in the build script.
Values for these properties are set by the first place they are
defined, from the following list:
* Definitions on the "ant" command line (ant -Dfoo=bar compile).
* Definitions from a "build.properties" file in the top level
source directory of this application.
* Definitions from a "build.properties" file in the developer's
home directory.
* Default definitions in this build.xml file.
You will note below that property values can be composed based on the
contents of previously defined properties. This is a powerful technique

set to the current working directory.

<!-- ===================== Property Definitions =========================== -->
<!--
Each of the following properties are used in the build script.
Values for these properties are set by the first place they are
defined, from the following list:
* Definitions on the "ant" command line (ant -Dfoo=bar compile).
* Definitions from a "build.properties" file in the top level
source directory of this application.
* Definitions from a "build.properties" file in the developer's
home directory.
* Default definitions in this build.xml file.
You will note below that property values can be composed based on the
contents of previously defined properties. This is a powerful technique
that helps you minimize the number of changes required when your development
environment is modified. Note that property composition is allowed within
"build.properties" files as well as in the "build.xml" script.

<!-- ==================== File and Directory Names ======================== -->
<!--
These properties generally define file and directory names (or paths) that
affect where the build process stores its outputs.
app.name Base name of this application, used to
construct filenames and directories.
Defaults to "myapp".
app.path Context path to which this application should be
deployed (defaults to "/" plus the value of the
"app.name" property).
app.version Version number of this iteration of the application.
build.home The directory into which the "prepare" and
"compile" targets will generate their output.
Defaults to "build".
catalina.home The directory in which you have installed
a binary distribution of Tomcat 4. This will
be used by the "deploy" target.
dist.home The name of the base directory in which
distribution files are created.
Defaults to "dist".
manager.password The login password of a user that is assigned the
"manager" role (so that he or she can execute
commands via the "/manager" web application)
manager.url The URL of the "/manager" web application on the
Tomcat installation to which we will deploy web
applications and web services.

Use property values to define the locations of external JAR files on which
your application will depend. In general, these values will be used for
two purposes:
* Inclusion on the classpath that is passed to the Javac compiler
* Being copied into the "/WEB-INF/lib" directory during execution
of the "deploy" target.
Because we will automatically include all of the Java classes that Tomcat 4
exposes to web applications, we will not need to explicitly list any of those
dependencies. You only need to worry about external dependencies for JAR
files that you are going to include inside your "/WEB-INF/lib" directory.
-->

<!-- ==================== Compilation Classpath =========================== -->
<!--
Rather than relying on the CLASSPATH environment variable, Ant includes
features that makes it easy to dynamically construct the classpath you
need for each compilation. The example below constructs the compile
classpath to include the servlet.jar file, as well as the other components
that Tomcat makes available to web applications automatically, plus anything
that you explicitly added.
-->

These properties control option settings on the Javac compiler when it
is invoked using the <javac> task.

compile.deprecation Should compilation include the deprecation option?
compile.optimize Should compilation include the optimize option?

HOW WEBGOAT WORKS
TROUBLESHOOTING/FAQs:
Q. I put the OWASP downloaded war file in my tomcat/webapps directory and the
http://localhost/WebGoat/attack url doesn't work.
A. Rename the downloaded war file to WebGoat.war. Delete the existing tomcat/webapps/*WebGoat* directories. Restart Tomcat.
Q. I dropped the WebGoat war file into my non-Tomcat application server and WebGoat doesn't seem to work.
A. WebGoat uses some of the internal Tomcat classes for user management. Unfortunately, this makes
WebGoat dependent on Tomcat. Hopefully, this will be addressed in a future release.
Q. Having problems with the ant file working properly. How do I configure my ant environment
so that I don't receive errors such as:
- "Specified VM install not found: type Standard VM, name j2sdk1.4.2.06"
A. This usually indicates an Eclipse environment setting misconfiguration. Here are some possible solutions:
i. Ant Runtime Configuration
- Window > Preferences
- Ant > Runtime
- Under Classpath Tab check the "Global Entries"
- Remove any jre "tools.jar" references
- Add the "\tomcat\servers\lib\catalina-ant.jar" file.
- Click Apply, Click OK.
- Return to the Ant View and refresh.
Q. When I start up WebGoat it dies very quickly.
A. WebGoat is a Java application that runs on Tomcat using port 80. If you have another
application listening on port 80 (like IIS), you will need to change WebGoat's port
(to 8080 or something) in the tomcat_root/conf/server.xml file.
Q. When I deploy the war file to the Tomcat wepapps directory, I can't login to WebGoat
A. You need to add the webgoat users and roles to tomcat/conf/tomcat-users.xml
<?xml version="1.0" encoding="UTF-8"?>
<tomcat-users>
<role rolename="webgoat_basic"/>
<role rolename="webgoat_admin"/>
<role rolename="webgoat_user"/>
<role rolename="tomcat"/>
<user password="webgoat" roles="webgoat_admin" username="webgoat"/>
<user password="basic" roles="webgoat_user,webgoat_basic" username="basic"/>
<user password="tomcat" roles="tomcat" username="tomcat"/>
<user password="guest" roles="webgoat_user" username="guest"/>
</tomcat-users>
Q. How do I get configure WebGoat to run on an IP other then localhost?
A. In the webgoat.bat file, in the root directory, the following lines
are executed:
delete .\tomcat\conf\server.xml
copy .\tomcat\conf\server_80.xml .\tomcat\conf\server.xml
This will overwrite any changes you may have made to server.xml
file that addressed this issue....
By changing the server_80.xml file (or by removing the above code
from webgoat.bat, after making your changes) you can reflect your
changes to the Tomcat configuration. You will need to change the IP
address in the server_80.xml file to be the IP of the host machine.
The following connectors should be modified
<!-- Define a non-SSL HTTP/1.1 Connector on port 8080 -->
<Connector address="10.20.20.123" port="80"
...
<!-- Define a SSL HTTP/1.1 Connector on port 8443 -->
<Connector address="10.20.20.123" port="443"
....
where the 127.0.0.1 will be replaced by your IP. In this case
10.20.20.123
Q. How do I solve lesson X?
