Kerentanan Weak Password Recovery Mechanism for Forgotten Password pada ctfd. Skor CVSS 3.1 9.8 (Critical) menurut NVD.
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.
