<bug_vulnerability_class>Wrong File Permission</bug_vulnerability_class>
<bug_description>The target system seems to be running a vulnerable old finger daemon. A special query beginning with a pipe sends the content of a file back. An attacker can read any file on the target system with commands like "finger |/etc/passwd@target".</bug_description>
<bug_solution>The finger service, if not needed, should be disabled (in /etc/inetd.conf) or if possible firewalled. Upgrade to the latest software version to be not vulnerable anymore.</bug_solution>
