Title

RHEL 10 must enforce mode "0740" or less permissive for local initialization files.

Control

Verify RHEL 10 is configured so that all local initialization files have a mode of "0740" or less permissive with the following command: Note: The example will be for the "disauser" user, who has a home directory of "/home/disauser". $ sudo find /home -maxdepth 2 -type f -name ".*" -exec stat -c "%n %a" {} \; | awk '$2 > 740' /home/disauser/.bash_profile 770 If any local initialization files are returned, this indicates a mode more permissive than "0740", and this is a finding.

Discussion

Local initialization files are used to configure the user's shell environment upon login. Malicious modification of these files could compromise accounts upon login.
