Описание
Improper Authentication in django-mfa3
Impact
django-mfa3 is a library that implements multi factor authentication for the django web framework. It achieves this by modifying the regular login view. Django however has a second login view for its admin area. This second login view was not modified, so the multi factor authentication can be bypassed.
You are affected if you have activated both django-mfa3 (< 0.5.0) and django.contrib.admin and have not taken any other measures to prevent users from accessing the admin login view.
Patches
The issue has been fixed in django-mfa3 0.5.0.
Workarounds
It is possible to work around the issue by overwriting the admin login route, e.g. by adding the following URL definition before the admin routes:
