SV-63839r1_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

Check the contents of user home directories for files with extended ACLs. # cut -d : -f 6 /etc/passwd | xargs -n1 -IDIR ls -alLR DIR If the permissions 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

Remove the extended ACL from the file. # 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.
