Detailed Explanation for this Vulnerability Assessment

Summary :

The rsh service is running.

Description :

The remote host is running the 'rsh' service. This service is dangerous in
the sense that it is not ciphered - that is, everyone can sniff the data
that passes between the rsh client and the rsh server. This includes logins
and passwords.

Also, it may permit poorly authenticated logins without passwords. If the
host is vulnerable to TCP sequence number guessing (from any network)
or IP spoofing (including ARP hijacking on a local network) then it may
be possible to bypass authentication.

Finally, rsh is an easy way to turn file-write access into full logins
through the .rhosts or rhosts.equiv files.

You should disable this service and use ssh instead.

Solution :

Comment out the 'rsh' line in /etc/inetd.conf
