Details

Incorrect username validation in the registration processes of CTFd through 2.2.2 allows a remote attacker to take over an arbitrary account after initiating a password reset. This is related to register() and reset_password() in auth.py. To exploit the vulnerability, one must register with a username similar to the admin, but with spaces inserted before and after the username. This will register the account with the same username as the admin. After a reset of the password for this new account, CTFd will reset the admin account's password due to the username collision.

Summary

Incorrect username validation in the registration process of CTFd v2.0.0 - v2.2.2 allows an attacker to take over an arbitrary account if the username is known and emails are enabled on the CTFd instance. To exploit the vulnerability, one must register with a username identical to the victim's username, but with white space inserted before and/or after the username. This will register the account with the same username as the victim. After initiating a password reset for the new account, CTFd will reset the victim's account password due to the username collision.
