A misconfiguration in /etc/sudoers allows members of group sudo to execute any command
1. Running the following command give us a hint
- sudo -l
2. In the /etc/sudoers, the configuration should show like this
- cat /etc/sudoers
3. We can also make sure our user is part of this group
1. Knowing the sudoers file allows all members of sudo group to execute any command with privilege rights, and making sure our user is part of this group, we can go ahead, and run for example bash as root
- sudo bash
Note: If (NOPASSWD) is specified within the configuration, then no need to use the user’s password.
Configure properly permissions to users that require, apply least privilege principles to each user that requires higher privileges.
