Title

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

Discussion

File system ACLs can provide access to files beyond what is allowed by the mode numbers of the files. The /etc/passwd file contains the list of local system accounts. It is vital to system security and must be protected from unauthorized modification.

Check Content

Verify /etc/passwd has no extended ACL. # ls -lL /etc/passwd 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 /etc/passwd
