miniOrange pre-login enrollment permits second-factor rebinding
miniOrange 2FA before 6.2.7 does not bind a newly configured second factor during the pre-login challenge to the target account's existing factor. An attacker who knows a user's password can redirect or re-enroll that user's second factor to an attacker-controlled destination, complete the challenge and obtain the account session, including an administrator session. This unscored record received deeper review because it bypasses the second authentication factor. The CNA does not disclose the challenge route, enrollment action or parameters.
