SIMATIC S7-1200 CPU V2 devices contain an insufficiently protected private key used for the Certificate Authority (CA) for HTTPS connections. Possession of this key could allow remote attackers to spoof the device's web server by creating a forged web server certificate. Siemens recommends specific countermeasures for products where fixes are not, or not yet available. Refer to the chapter Additional Information for more details.
