Kelvin: This is what's typically called a layer 8 issue, or PEBKAC. It just means that you're failing to understand how bash works.
If you write a script that runs: #!/bin/bash sudo poweroff Is that a vulnerability? No! The script does exactly what you wrote, that is, to shutdown the machine. So, if you write a script without properly quoting $@ and $*, if you use `...` without regarding safety and other shell scripting pitfalls, is that a vulnerability? No! It just means that you have to try harder and learn bash :) -- Eduardo Bustamante https://dualbus.me/
