Title

The /etc/shadow file must not have an extended ACL. (Cat II impact)

Discussion

The /etc/shadow file contains the list of local system accounts. It is vital to system security and must be protected from unauthorized modification. The file also contains password hashes which must not be accessible to users other than root.

Check Content

Verify /etc/shadow has no extended ACL. # ls -lL /etc/shadow If the permissions include a '+', the file has an extended ACL and this is a finding.

Fix Text

Remove the extended ACL from the file. # getfacl /etc/shadow Remove each ACE returned. # setfacl -d [ACE] /etc/shadow
