Description
The fingerd daemon provides the server function for the finger command. This allows users to view real-time pertinent user login information on other remote systems. This service should be disabled as it may provide an attacker with a valid user list to target.
ℹ️ Check
From the command prompt, execute the following command:
# grep "^finger[[:blank:]]" /etc/inetd.conf
If there is any output from the command, this is a finding.
✔️ Fix
In "/etc/inetd.conf", comment out the "finger" entry by running command:
# chsubserver -r inetd -C /etc/inetd.conf -d -v 'finger' -p 'tcp'
Restart inetd:
# refresh -s inetd
