SV-45029r1_rule User home directories must not have extended ACLs.

Vulnerability discussion

Excessive permissions on home directories allow unauthorized access to user files.

Check content

Verify user home directories have no extended ACLs. # cut -d : -f 6 /etc/passwd | xargs -n1 ls -ld If the permissions include a '+', the file has an extended ACL this is a finding.

Fix text

Remove the extended ACL from the file. # setfacl --remove-all [user home directory with extended ACL]

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.
