This allowed a man-in-the-middle attacker to obtain an email-validated S/MIME certificate from a trusted CA and replace the public key of the entity to be impersonated. This enabled the attacker to decipher further communication. The entire attack could be accomplished by sending a single email."

Esto permiti\u00f3 a un atacante de tipo man-in-the-middle obtener un certificado S/MIME comprobado por correo electr\u00f3nico de una CA confiable y reemplazar la clave p\u00fablica de la entidad a ser suplantada. Esto permiti\u00f3 al atacante descifrar m\u00e1s comunicaciones. Todo el ataque podr\u00eda ser logrado mediante el env\u00edo de un solo correo electr\u00f3nico."
