Overview

🚩 CTF Leaderboard

The goal of this project is to provide a simple web page to allow the participants of an CTF to enter their found flags. Also the live overview over all found flags gives a more competitive feeling to the game.

This app is written using Python 3 and the Django web framework.

Screenshot

Features

  • Participants can submit flags found during the CTF challenge
  • Live reload on the leaderboard overview
  • Simple administration through the Django admin UI (at /admin)
  • Custom landing page through the Content-model in the DB for instructions, links and screenshots

Getting started

Create and activate a virtual environment for the app:

$ python3 -m venv venv
$ source venv/bin/activate

Install all the necessary dependencies:

$ python3 -m pip install -r requirements.txt

Copy the .env.dist file to a .env file and make suitable adjustments (SECRET_KEY is important).

Create the database through migration and create a superuser for the admin UI (at /admin):

$ python3 manage.py migrate
$ python3 manage.py createsuperuser
$ python3 manage.py collectstatic

Run the server:

$ python3 manage.py runserver

Participant-Name-Format (name e.g. "Group B" in the screenshot): max. 20 chars
Name-Format (custom_name e.g. "Maurice, Gabriel" in the screenshot): max. 40 chars [a-zA-Z0-9_ ,]*
Flag-Format (secret): max. 200 chars [a-zA-Z0-9_]+

Feature ideas

This is a list of features some users requested but still need to be implemented. Feel free to implement one of them and submit a pull request. Thank you! Hint: we are roughly following the PEP 8 guideline using autopep8.

  • Crown the winner of the CTF who first found all the flags
  • Allow the creation of multiple pages (not only one homepage)
  • Enable multiple simultaneous CTFs through a list of available CTFs or unique URLs
