SV-46119r1_rule The Network File System (NFS) export configuration file must have mode 0644 or less permissive.

Vulnerability discussion

Excessive permissions on the NFS export configuration file could allow unauthorized modification of the file, which could result in Denial of Service to authorized NFS exports and the creation of additional unauthorized exports.

Check content

# ls -lL /etc/exports If the file has a mode more permissive than 0644, this is a finding.

Fix text

# chmod 0644 /etc/exports

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.
