SV-64363r1_rule The root accounts home directory must not have an extended ACL.

Vulnerability discussion

File system extended ACLs provide access to files beyond what is allowed by the UNIX permissions of the files.

Check content

Check the root account's home directory has no extended ACL. # find ~root -type d -prune -exec ls -ld {} \; If the permissions include a '+' the directory has an extended ACL. If the file has an extended ACL and it has not been documented with the IAO, this is a finding.

Fix text

Remove the extended ACL from the root account's home directory. # setfacl --remove-all

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.
