Vulnerability discussion

Excessive permissions allow unauthorized access to user files.

Check content

Check the contents of user home directories for files with extended ACLs. Procedure: # cat /etc/passwd | cut -f 6,6 -d ":" | xargs -n1 -IDIR aclget DIR OR #aclget / Check if extended permissions are disabled. If extended permissions are not disabled, this is a finding.

Fix text

Remove the extended ACL(s) from the files and directories in user home directories and disable extended permissions. #acledit /

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.
