SV-86925r1_rule The Trivial File Transfer Protocol (TFTP) server package must not be installed if not required for operational support.

Vulnerability discussion

If TFTP is required for operational support (such as the transmission of router configurations) its use must be documented with the Information System Security Officer (ISSO), restricted to only authorized personnel, and have access control rules established.

Check content

Verify a TFTP server has not been installed on the system. Check to see if a TFTP server has been installed with the following command: # yum list installed tftp-server tftp-server-0.49-9.el7.x86_64.rpm If TFTP is installed and the requirement for TFTP is not documented with the ISSO, this is a finding.

Fix text

Remove the TFTP package from the system with the following command: # yum remove tftp

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.
