(in version v1 r3)
Title
The /etc/hosts file must be group-owned by bin, sys, or system. (Cat II impact)
Discussion
The /etc/hosts file (or equivalent) configures local host name to IP address mappings that typically take precedence over DNS resolution. If this file is maliciously modified, it could cause the failure or compromise of security functions requiring name resolution, which may include time synchronization, centralized authentication, and remote system logging.
Check Content
Check the /etc/hosts file's group ownership. Procedure: # ls -lL /etc/hosts If the file is not group-owned by bin, sys, or system, this is a finding.
Fix Text
Change the group owner of the /etc/hosts file to sys, bin, or system. Procedure: # chgrp system /etc/hosts
