| Description |
|---|
| If a user is assigned the GID of a group not existing on the system, and a group with that GID is subsequently created, the user may have unintended rights to the group. |
| ℹ️ Check |
|---|
| Verify that there are no GIDs referenced in "/etc/passwd" that are not defined in "/etc/group": # cut -d: -f4 /etc/passwd 0 1 2 3 4 203 204 # cut -d: -f3 /etc/group 0 1 2 3 4 203 204 If there are GID's listed in the "/etc/passwd" file that are not listed in the "/etc/group" file, this is a finding. |
| ✔️ Fix |
|---|
| Add a group to the system for each GID referenced without a corresponding group by running "mkgroup" command. |
