SV-45902r1_rule The TFTP daemon must have mode 0755 or less permissive.

Vulnerability discussion

If TFTP runs with the setuid or setgid bit set, it may be able to write to any file or directory and may seriously impair system integrity, confidentiality, and availability.

Check content

Check the mode of the TFTP daemon. Procedure: # grep "server " /etc/xinetd.d/tftp # ls -lL If the mode of the file is more permissive than 0755, this is a finding.

Fix text

Change the mode of the TFTP daemon. Procedure: # chmod 0755

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.
