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

Change the mode of the file "/etc/gshadow-" to "0000" by running the following command:

$ chmod 0000 /etc/gshadow-

Fix

Verify that the "/etc/gshadow-" file has mode "0000" with the following command:

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

0 /etc/gshadow-

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