Raw Blame History

1.2.0 / 2018-05-04

General

  • Updated to Flask 1.0 & switched documentation to suggest using flask run instead of python serve.py.
  • Added the ability to make static & regex flags case insensitive.
  • The /chals endpoint no longer lists the details of challenges.
    • The /chals/:id endpoint is now used to load challenge information before display.
  • Admins can now see what users have solved a given challenge from the admin panel.
  • Fixed issue with imports extracting files outside of the CTFd directory.
  • Added import zipfile validation and optional size restriction.
  • The ctftime, authentication, and admin restrictions have been converted to decorators to improve code reuse.
    • 403 is now a more common status code. Previously it only indicated CSRF failure, now it can indicate login failure or other Forbidden access situations.
  • Challenge previews now work consistently instead of occasionally failing to show.
  • Tests are now randomly ordered with nose-randomly.

Themes

  • Admins now have the ability to upload a CTF logo from the config panel.
  • Switched from the marked library to Markdown-It for client side markdown rendering.
    • This will break Challenge type plugins that override the markdown renderer since we are no longer using the marked renderers.
  • Introduced the ezpg() JS function to make it easier to draw a progressbar modal.
  • Introduced the $.patch() AJAX wrapper.
  • Team names are truncated properly to 50 characters in teams.html.
  • The admin panel now uses Bootstrap badges instead of buttons to indicate properties such as admin, verified, visible.

Plugins

  • Challenge type plugins now use a global challenge object with exposed functions to specify how to display a challenge. (preRender(), render(), postRender(), submit()).
    • Challenge type plugins also have access to window.challenge.data which allow for the previously mentioned functions to process challenge data and change logic accordingly.
  • Challenge type plugins now get full control over how a challenge is displayed via the nunjucks files.
  • Challenge plugins should now pass the entire flag/key object to a Custom flag type.
    • This allows the flag type to make use of the data column to decide how to operate on the flag. This is used to implement case insensitive flags.
  • Challenge modals (modal.njk) now use {{ description }} instead of {{ desc }} properly aligning with the database schema.
  • The update and create modals now inject data into the modal via nunjucks instead of client side Javascript.
  • The utils.base64decode() & utils.base64encode() functions no longer expose url encoding/decoding parameters.
