Title

The portmap or rpcbind service must not be installed unless needed. (Cat II impact)

Discussion

The portmap and rpcbind services increase the attack surface of the system and should only be used when needed. The portmap or rpcbind services are used by a variety of services using Remote Procedure Calls (RPCs).

Check Content

If the system needs the portmap service to operate, this is not applicable. In order to inspect the HP-UX portmapper protocol: # rpcinfo -p If the service is running while supporting a required service, i.e., mountd/nfs(d), this is not a finding. If the portmap service is installed/running and not required to support any service(s), this is a finding.

Fix Text

If the portmap or rpcbind service is part of a removable package, consult vendor documentation for the procedure to remove the package. If the service cannot be removed, prevent service activation by removing all permissions from the executable. Procedure: # whereis rpcinfo # chmod 0000 <daemon path/filename from the above command>
