Hi All As you all know a non root user can not run iftop. So the most obvious workaround is to use sudo. Now if you give a regular user sudo access he will execute.
sudo iftop
Once he is inside iftop. He can execute ! he will get the following promtp
command >
At this point a user can execute su, and he will get a root shell. He can also execute any command in privileged mode. The idea of using sudo initially was giving the user iftop access. However the user ends up with total root access.
Please comment.
