Searches for the existence of daytime 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. Network Security Threat Level: None / CVSS Base Score : 0 (AV:R/AC:L/Au:NR/C:N/A:N/I:N/B:N) Networks Security ID: Vulnerability Assessment Copyright: This script is Copyright (C) 1999 Renaud Deraison |
