RHEL 10 must enforce mode "0000" or less permissive for the "/etc/gshadow-" file to prevent unauthorized access.

STIG ID: RHEL-10-400260  |  SRG: SRG-OS-000080-GPOS-00048 |  Severity: medium (CAT II)  |  CCI: CCI-000213 |  Vulnerability Id: V-281069

Vulnerability Discussion

The "/etc/gshadow-" file is a backup of "/etc/gshadow", and as such contains group password hashes. Protection of this file is critical for system security.

Check

Verify RHEL 10 is configured so that the "/etc/gshadow-" file has mode "0000" with the following command:

$ sudo stat -c "%a %n" /etc/gshadow-
0 /etc/gshadow-

If a value of "0" is not returned, this is a finding.

Fix

Configure RHEL 10 so that the mode of the "/etc/gshadow-" file is set to "0000" by running the following command:

$ sudo chmod 0000 /etc/gshadow-
