Descriptions
strongSwan 4.3.0 through 5.x before 5.3.2 and strongSwan VPN Client before 1.4.6, when using EAP or pre-shared keys for authenticating an IKEv2 connection, does not enforce server authentication restrictions until the entire authentication process is complete, which allows remote servers to obtain credentials by using a valid certificate and then reading the responses.
strongSwan 4.3.0 hasta 5.x anterior a 5.3.2 y strongSwan VPN Client anterior a 1.4.6, cuando utiliza claves EAP o precompartidas para la autenticación de una conexión IKEv2, no refuerza las restricciones de autenticación de servidores hasta que el proceso de autenticación entero se haya completado, lo que permite a servidores remotos obtener credenciales mediante el uso de un certificado válido y posteriormente la lectura de las respuestas.
