Technical Details

what runs on :22351

TCP port 22351 is assigned to CodeMeter CM-WAN, WIBU-SYSTEMS' service for TCP/IP requests from copy-protection software to a server. CodeMeter-protected applications use the service to request network license access; this is a proprietary application protocol, not a general-purpose web service. The commonly associated CodeMeter Runtime Server service uses TCP 22350, but that is a separate port and assignment.

security overview

This service can expose a network license server to remote clients, so keep it limited to systems that need licensing access and filter it with firewall rules or a VPN rather than exposing it broadly to the internet. It is not a general remote-administration interface; the assignment alone does not establish that the connection is encrypted or provide evidence of a specific vulnerability.
