The vulnerability affects the following NGFW features when the LDAP authentication method is used as the backend authentication: IPsec VPN, SSL VPN or Browser-based user authentication. The vulnerability does not apply when any other backend authentication is used. The RADIUS authentication method is not vulnerable, for example."

La vulnerabilidad afecta las siguientes características de NGFW cuando se utiliza el método de autenticación LDAP como autenticación de back-end: IPsec VPN, SSL VPN o autenticación de usuario basada en navegador. La vulnerabilidad no se aplica cuando se utiliza cualquier otra autenticación de back-end. El método de autenticación RADIUS no es vulnerable, por ejemplo."
