A Simple Method for Fingerprinting SAP BusinessObjects

The main component of a BusinessObjects installation is the Central Management Server (CMS). It’s rarely changed and default TCP port is 6400. A simple way to identify if you are communicating with a BusinessObjects installation is to make a socket connection to the remote server and send the string ‘aps’. If everything is running correctly you should receive the IOR of the CMS.

Note that the hostname of the server is given at the end of the response which is useful in further attacks. Furthermore, if you parse the IOR you will get the IP and port of the CMS’s dynamic listening port which can be added to your Reconnaissance data.

A note on Defense

The most critical point of prevention is firewalling the CMS from unauthorized connections.
