SV-38095r1_rule All files and directories contained in user home directories must not have extended ACLs.

Vulnerability discussion

Excessive permissions allow unauthorized access to user files.

Check content

Open a terminal session and enter the following command. find /Users -print -exec ls -lLd \{\} \; | grep '^..........+' If files are shown with permissions that include a '+', the file 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

Open a terminal session and enter the following command to remove the extended ACLs. chmod -N

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.
