Description :

The remote host is running a 'finger' service that suffers from an
information disclosure vulnerability. Specifically, it permits an
unauthenticated attacker to display a list of accounts on the remote
host that have never been used. This list can help a possible hacker to
guess the operating system type and also focus his attacks.

Solution :

Filter access to this port, upgrade the finger server, or disable it
entirely.
