description

SOGo versions before 5.12.13 do not apply failed-login limits to web TOTP verification attempts. An attacker who already has a user's password may repeatedly guess the second-factor code and potentially bypass two-factor authentication.

mitigation

Upgrade SOGo to version 5.12.13 or later. Until upgraded, reduce exposure to the web login service and monitor for repeated failed TOTP verification attempts.

fixed in 5.12.13
