Descriptions

Citrix ShareFile before 19.23 allows a downgrade from two-factor authentication to one-factor authentication. An attacker with access to the offline victim's otp physical token or virtual app (like google authenticator) is able to bypass the first authentication phase (username/password mechanism) and log-in using username/otp combination only (phase 2 of 2FA).

Citrix ShareFile hasta la versión 19.23, permite una degradación de la autentificación de dos factores a la autorización de un factor. Un atacante con acceso al token físico o a la aplicación virtual OTP de la víctima sin conexión (como el identificador de google) es capaz de omitir la primera fase de identificación (mecanismo de nombre de usuario y contraseña) e iniciar sesión utilizando solo la combinación de nombre de usuario y OTP (fase 2 de 2FA).
