CWE-290: Authentication Bypass by Spoofing vulnerability exists that could cause a denial of service and loss
of confidentiality and integrity of controllers when conducting a Man-In-The-Middle attack between the
controller and the engineering workstation while a valid user is establishing a communication session. This
vulnerability is inherent to Diffie Hellman algorithm which does not protect against Man-In-The-Middle attacks.
