SV-86923r2_rule A File Transfer Protocol (FTP) server package must not be installed unless needed.

Vulnerability discussion

The FTP service provides an unencrypted remote access that 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. SSH or other encrypted file transfer methods must be used in place of this service.

Check content

Verify an FTP server has not been installed on the system. Check to see if an FTP server has been installed with the following commands: # yum list installed vsftpd vsftpd-3.0.2.el7.x86_64.rpm If "vsftpd" is installed and is not documented with the Information System Security Officer (ISSO) as an operational requirement, this is a finding.

Fix text

Document the "vsftpd" package with the ISSO as an operational requirement or remove it from the system with the following command: # yum remove vsftpd

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.
