SV-40307r2_rule The NFS server must not allow remote root access.

Vulnerability discussion

If the NFS server allows root access to local file systems from remote hosts, this access could be used to compromise the system.

Check content

Determine if the NFS server is exporting with the root access option. Procedure: # exportfs -v | grep "root=" OR # more /etc/dfs/sharetab If an export with the root option is found and is not properly documented with the IA staff, this is a finding.

Fix text

Edit the /etc/dfs/dfstab file and remove the root= option from all exports. Re-export the file systems.

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.
