| Description |
|---|
| The sudo command allows a user to execute programs with elevated (administrator) privileges. It prompts the user for their password and confirms the request to execute a command by checking a file, called sudoers. If the "sudoers" file is not configured correctly, any user defined on the system can initiate privileged actions on the target system. |
| ℹ️ Check |
|---|
| Verify the "sudoers" file restricts sudo access to authorized personnel. $ sudo grep -iwr 'ALL[[:blank:]]\+ALL' /etc/sudoers /etc/sudoers.d If the either of the following entries are returned, this is a finding: ALL ALL=(ALL) ALL ALL ALL=(ALL:ALL) ALL |
| ✔️ Fix |
|---|
| Remove the following entries from the sudoers file: ALL ALL=(ALL) ALL ALL ALL=(ALL:ALL) ALL |
