Detailed Explanation for this Vulnerability Assessment

Summary :

A daytime service is running on the remote host

Description :

The remote host is running a 'daytime' service. This service
is designed to give the local time of the day of this host
to whoever connects to this port.

The date format issued by this service may sometimes help a possible hacker
to guess the operating system type of this host, or to set up
timed authentication attacks against the remote host.

In addition to that, the UDP version of daytime is running, a possible hacker
may link it to the echo port of a third party host using spoofing, thus
creating a possible denial of service condition between this host and
a third party.

Solution :

- Under Unix systems, comment out the 'daytime' line in /etc/inetd.conf
and restart the inetd process

- Under Windows systems, set the following registry keys to 0 :
HKLM\System\CurrentControlSet\Services\SimpTCP\Parameters\EnableTcpDaytime
HKLM\System\CurrentControlSet\Services\SimpTCP\Parameters\EnableUdpDaytime

Then launch cmd.exe and type :

net stop simptcp
net start simptcp

To restart the service.
