RHEL 10 must be configured so that library directories are group-owned by "root" or a system account.

STIG ID: RHEL-10-400125  |  SRG: SRG-OS-000259-GPOS-00100 |  Severity: medium (CAT II)  |  CCI: CCI-001499 |  Vulnerability Id: V-281042

Vulnerability Discussion

If RHEL 10 allowed any user to make changes to software libraries, those changes might be implemented without undergoing the appropriate testing and approvals that are part of a robust change management process.

This requirement applies to RHEL 10 with software libraries that are accessible and configurable, as in the case of interpreted languages. Software libraries also include privileged programs that execute with escalated privileges.

Check

Verify RHEL 10 is configured so that the systemwide shared library directories are group-owned by "root" or a system account with the following command:

$ sudo find /lib /lib64 /usr/lib /usr/lib64 ! -group root -type d -exec stat -c "%G %n" {} \;

If any systemwide shared library directory is returned and is not group-owned by "root" or a required system account, this is a finding.

Fix

Configure RHEL 10 so that the systemwide shared library directories (/lib, /lib64, /usr/lib and /usr/lib64) are protected from unauthorized access.

Run the following command, replacing "[DIRECTORY]" with any library directory not group-owned by "root".

$ sudo chgrp root [DIRECTORY]
