Title

The NFS export configuration file must have mode 0644 or less permissive. (Cat III impact)

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/dfs/dfstab If the file has a mode more permissive than 0644, this is a finding.

Fix Text

Change the permissions of the dfstab file to 664 or less permissive. # chmod 0644 /etc/dfs/dfstab
