RHEL-10-400270 - RHEL 10 must enforce mode "0644" or less permissive for "/etc/passwd-" file to prevent unauthorized access.

Information

The "/etc/passwd-" file is a backup file of "/etc/passwd", and as such contains information about the users that are configured on the system. Protection of this file is critical for system security.

Solution

Configure RHEL 10 so that the mode of the "/etc/passwd-" file is set to "0644" by running the following command:

$ sudo chmod 0644 /etc/passwd-
