Notch: A Vulnerable Application

Notch is a vulnerable PHP-based application only to be used for training purposes. DO NOT deploy this application in a production environment as it has many known vulnerabilities that could lead to a compromise of your system., _(*1)

Manual installation

You can install a Notch instance manually in a few simple steps:, _(*2)

1. git clone the repo into a web accessible directory, like /var/www/notch
2. Run a composer.phar install to get all dependencies
3. Create the database needed:

mysqladmin create notch;
mysql -u root -p -e "grant all on notch.* to 'notch'@'localhost' identified by 'notch42'";

1. Run the migrations: vendor/bin/phinx migrate

This should get you up and running with your basic site and a bit of content., _(*3)

Vagrant installation

A Vagrant setup has been provided in the vagrant/ directory making it a one command install once it's cloned:, _(*4)

cd vagrant; vagrant up

One thing to note here though - the Vagrant setup uses name-based virtual hosts, so you'll need to add this to your /etc/hosts:, _(*5)

• Broken Authentication & Session Management (A2)
• Cross-site scripting (A3)

• Sensitive Data Exposure (A6)

There are places in the application where comments with the word "Hint" have been placed to help guide you to locate the issues. As this is being used for a tutorial at the PHP Benelux conference, I'm not going to show them just yet :), _(*7)
