Summary
Hitachi Energy is aware of a reported vulnerability in the RTU500 Scripting interface. When a client connects to a server using TLS, the server presents a certificate. This certificate links a public key
to the identity of the service and is signed by a Certification Authority (CA), allowing the client to validate that the remote service can be trusted and is not malicious. If the client does not validate the parameters of the certificate, then attackers could be able to spoof the identity of the service.
