Title

All shell files must be group-owned by root, bin, sys, or system. (Cat II impact)

Discussion

If shell files are group-owned by users other than root or a system group, they could be modified by intruders or malicious users to perform unauthorized actions.

Check Content

If /etc/shells exists, check the group ownership of each shell referenced. Procedure: # cat /etc/shells | xargs -n1 ls -lL Otherwise, check any shells found on the system. Procedure: # find / -name "*sh" | xargs -n1 ls -lL If a shell is not group-owned by root, bin, sys, or other, this is a finding.

Fix Text

Change the group owner of the shell to root, bin, sys, or other. Procedure: # chgrp root <shell>
