Technical Details

what runs on :6400

Port 6400 is the default CMS contact port for SAP BusinessObjects Enterprise/BI platform. In normal deployments it is used over TCP, although the IANA registration does not specify a transport. Clients and platform services connect to the CMS to access BI system metadata and security information and to coordinate platform operations. The port can be changed, and TLS can be configured; communication is not encrypted by default in a typical installation.

security overview

Keep this service on trusted internal networks rather than exposing it to the internet: it is a central BI platform service and can reveal or manage sensitive system and security information to authenticated clients. An exposed instance also gives attackers a target for credential attacks and for vulnerabilities in the deployed SAP BusinessObjects version; use current patches and restrict access with firewalls.
