SV-38281r1_rule All system command files must not have extended ACLs.

Vulnerability discussion

Restricting permissions will protect system command files from unauthorized modification. System command files include files present in directories used by the operating system for storing default system executables and files present in directories included in the system's default executable search paths.

Check content

Verify all system command files have no extended ACLs. # ls -lL /etc /bin /usr/bin /usr/lbin /usr/usb /sbin /usr/sbin If the permissions include a "+", the file has an extended ACL, this is a finding.

Fix text

Remove the optional ACL from the file. # chacl -z /

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.
