An identity-verification weakness in Kiteworks Email Protection Gateway allowed the gateway to act on the Kiteworks platform on behalf of a user it had not authenticated, and to provision a platform account for an identity it did not already know. A remote, unauthenticated sender could potentially exploit this to obtain control of a platform account.
