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 the /etc/passwd file has no extended ACL. Procedure: #aclget /etc/passwd Check to see if extended permissions are disabled. If extended permissions are not disabled, this is a finding.
Fix Text
Remove the extended ACL from the /etc/passwd file and disable extended permissions. #acledit /etc/passwd
