Vulnerability from github – Published: 2024-11-13 06:30 – Updated: 2024-11-13 06:30

Details

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.
