Vulnerability Assessment Details

Finger dot at host feature

Vulnerability Assessment Summary
Finger .@host feature

Detailed Explanation for this Vulnerability Assessment


There is a bug in the remote finger service which, when triggered, permits
a user to force the remote finger daemon to display the list of the accounts
that have never been used, by issuing the request :

finger .@target

This list will help a possible hacker to guess the operating system type. It will
also tell him which accounts have never been used, which will often make him
focus his attacks on these accounts.

Solution : disable the finger service in /etc/inetd.conf and restart the inetd
process, or upgrade your finger service.

Network Security Threat Level: Medium
