      "value": "A vulnerability in the EnableTwoFactorAuthRequest SOAP endpoint of Zimbra Collaboration (ZCS) allows an attacker with valid user credentials to bypass Two-Factor Authentication (2FA) protection. The attacker can configure an additional 2FA method (either a third-party authenticator app or email-based 2FA) without presenting a valid authentication token or proving access to an already configured 2FA method. This bypasses 2FA and results in unauthorized access to accounts that are otherwise protected by 2FA."

      "value": "Una vulnerabilidad en el endpoint SOAP EnableTwoFactorAuthRequest de Zimbra Collaboration (ZCS) permite a un atacante con credenciales de usuario válidas eludir la protección de autenticación de dos factores (2FA). El atacante puede configurar un método 2FA adicional (ya sea una aplicación de autenticación de terceros o 2FA basada en correo electrónico) sin presentar un token de autenticación válido o probar el acceso a un método 2FA ya configurado. Esto elude el 2FA y resulta en acceso no autorizado a cuentas que de otro modo están protegidas por 2FA."
