SV-45809r1_rule The telnet daemon must not be running.

Vulnerability discussion

The telnet daemon provides a typically unencrypted remote access service which does not provide for the confidentiality and integrity of user passwords or the remote session. If a privileged user were to log on using this service, the privileged user password could be compromised.

Check content

# chkconfig --list | grep telnet If an entry is returned and any run level is “on” telnet is running. If the telnet daemon is running, this is a finding.

Fix text

Identify the telnet service running and disable it. Procedure # insserv –r telnetd If telnet is running as an xinetd service, edit the /etc/xinetd.d file and set “disable = yes” and then restart the xinetd service: # rcxinetd restart disable the telnet server: chkconfig telnet off verify the telnet daemon is no longer running: # ps -ef |grep telnet

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
