  • Siemens products that contain a vulnerable TLS client: in cases where this option is configurable: ensure that TLS server certificate verification is turned on and do not configure trust for CA certificates, that contain a nameConstraint-extension (https://www.rfc-editor.org/rfc/rfc5280#section-4.2.1.10) with punycode-encoded internationalized domain names
  • As a mitigation for vulnerable versions: Ensure that only trusted (CA) certificates are contained in the Machine Agent's truststore
