What is this

This is Max Kellermann's exploit POC for DirtyPipe, but modified to overwrite root's password field in /etc/passwd and restore after popping a shell.

How to use this

Run ./compile.sh then ./exploit and it'll pop a root shell.

su: must be run from a terminal

If you get this error message, login as root with the password aaron.
Then, restore /etc/passwd by running mv /tmp/passwd.bak /etc/passwd
