But in the affected systems section it states:
> Also Hitachi Energy RTU500 firmware and Siemens Ruggedcom APE1808 firmware.
I cannot find any reference that this Hitachi device is vulnerable to that CVE. Hitachi has a nice interface to list all vulnerabilities of their devices, this CVE is not part of it. In the Mitigation section any mention of Hitachi is also missing. Almost as if this device is not vulnerable.
There is some more weirdness, like it doesn't mention the "portal" feature is also vulnerable.
