Detailed Explanation for this Vulnerability Assessment

anyone to get the lists of the users of this system, when
issuing the command :

finger search.**@victim

This information can in turn be used by a possible hacker to set up
a brute force login attack against this host.

Solution : use another finger daemon or disable this service in /etc/inetd.conf
