Who should care
Administrators and users of Termix, especially those who rely on 2FA for security, should be aware of this vulnerability. It is crucial for them to update to version 2.3.2 or later to mitigate the risk.
Technical summary
The `POST /users/totp/disable` and `POST /users/totp/backup-codes` endpoints in Termix prior to version 2.3.2 do not properly enforce multi-factor authentication for critical operations. An attacker who obtains a user's password can exploit this weakness to disable TOTP or regenerate backup codes without needing the TOTP device or a valid TOTP code. This effectively bypasses 2FA protection.
Defensive priority
High
Recommended defensive actions
- Update Termix to version 2.3.2 or later.
- Review and enforce strong password policies.
- Educate users about the importance of 2FA and phishing risks.
