The I/O-Check service protocol is only needed during installation and commissioning, not during normal operations. It is highly recommended to disable the IP-port 6626 after commissioning. This is the easiest and securest way to protect your device for the listed vulnerabilities and for upcoming zero day exploits. Regardless of the action described above, the following CVEs can be fixed alternatively by a firmware update >= FW 15. CVE-2019-5073 CVE-2019-5074 CVE-2019-5075 CVE-2019-5079 CVE-2019-5081 CVE-2019-5082
