Vulnerability discussion

The POP3 service is only needed if the server is acting as a mail server and clients are using applications that only support POP3. Users' ids and passwords are sent in plain text to the POP3 service. If mail client access is needed, consider using IMAP or SSL enabled POP3.

Check content

Check the '/etc/inetd.conf' file for active POP3 service. #grep pop3 /etc/inetd.conf | grep -v \# If the POP3 service is enabled, this is a finding.

Fix text

Edit /etc/inetd.conf and comment out POP3 the service line. Restart the inetd service. # refresh -s inetd

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.
