Add CTFd 2.x as distinct framework

[bkimminich]

• [x] Identify and list all breaking changes between CTFd 1.x and 2.x data models (https://github.com/CTFd/CTFd/blob/master/CHANGELOG.md)
• [x] Add CTFd 2.x as a separate framework with its own generators (or shared where possible with 1.x)
• [ ] Rename CTFd framework option into CTFd 1.x
• [ ] Make CTFd 1.x the default selection and also map the old alias CTFd to it (for non-breaking change of existing config files - but with deprecation warning upon parsing)

CTFd 2.x exports and imports all tables by default. A possible solution would be to export an "empty" CTFd setup with only the mininum required data (i.e. an admin user, a CTF title etc.) and let the util overwrite the challenges.json, keys.json and hints.json files in the ZIP.

:interrobang: @ColdHeat, this would probably overwrite all data someone might already have put in manually, including all users and admin account etc. Is there any way to prevent this from happening?

[ColdHeat]

I think the first thing to know is that while generated exports have every table, the importer doesn't require all tables to exist.

You could generate an import with only challenges.json, flags.json, hints.json, files.json and other juice shop relevant tables. After importing the tables that weren't inside of the zip file won't be affected.

This would work well for situations where the user is importing from the command line because they could modify or otherwise run the import.py script without triggering a database wiping. However, this isn't the same for importing via the web UI where deleting the database before import is difficult to avoid at the moment. I think the best thing to do in that scenario is to allow the wipe to happen and let the import import all challenges but require the user to re-create the admin account and others.

[bkimminich]

Ok, this is exactly what my tool generates, a ZIP with only those tables. But upon UI import there is an error being thrown: KeyError("There is no item named 'db/alembic_version.json' in the archive",) - after that happened all subsequent requests for any pages will end in an Internal Server Error. In the server log I saw OperationalError: (sqlite3.OperationalError) no such table: config [SQL: u'SELECT config.id AS config_id, config."key" AS config_key, config.value AS config_value \nFROM config \nWHERE config."key" = ?\n LIMIT ? OFFSET ?'] [parameters: ('ctf_name', 1, 0)] (Background on this error at: http://sqlalche.me/e/e3q8) then.

So, do I have to provide all other .json files as empty to make the new importer happy?

This is a sample export file my tool generates at the moment, which works up to CTFd 1.2.0 just fine.

[ColdHeat]

You need to migrate the tables that are output because there are significant changes in database structure between 1.2.0 and 2.0.0.

You should look at the 1.2.0 -> 2.0.0 migration script: https://github.com/CTFd/CTFd/blob/master/migrations/1_2_0_upgrade_2_0_0.py

And also the new CTFd models: https://github.com/CTFd/CTFd/blob/master/CTFd/models/__init__.py

Also you do now need to provide db/alembic_version.json but you should be okay to use the alembic_version that's currently in use (8369118943a1) because we should now be able to accept imports from previous version if we do upgrade.

You could try importing your 1.2.0 export into a 1.2.0 CTFd, then using python migrations/1_2_0_upgrade_2_0_0.py, and then exporting to see the difference in what is generated.

[mmmod]

A workaround at this point is to run 1.2.0 of CTFd, import seems to work:

• Checkout 1.2.0 of CTFd from the repo
• Change db image in docker-compose to "mariadb:10.4" (from mariadb:10.2)

[bkimminich]

Official supported CTFd versions are 1.1.x and 1.2.x at the moment, and they should work out of the box. At least with the singular ctfd/ctfd Docker image.

@bkimminich I think you might have removed your previous comment but I don't believe getting all of the setup data from the user at creation time is necessary.

I think I would just output a the zip with the json files that you want. The others should be ignored by the importer if they're missing.

Also the import_ctf() function has a parameter to control whether or not we erase. Erasing is safer overall but we could modify the command line importer to make erasing optional if it's helpful.

[bkimminich]

@ColdHeat, thanks, I wrote the now-deleted comment before trying out what you suggested, and that did it. Except for the fact that after import an Internal Server Error pops up and the CTFd server needs a restart. But then all seems okay once you set up your CTF name and admin account again.

I attached a ZIP for CTFd 2.x, so if you can give me any hint what to add in order to prevent this error, I'll happily change my tool a bit.

This might be a bug in CTFd ultimately but you can fix it by providing a config.json with ctf_theme set to core.

Importing from the command line worked fine for me.
