ttyinject-rs
→ View on GitHubttyinject-rs is a tool that exploits the `TIOCSTI` ioctl in the Linux kernel to inject keystrokes into a terminal, allowing a non-privileged user to gain root privileges when the root user executes `su - user`. Notable features include its easy integration with a user's `~/.bashrc`, its self-deleting behavior post-execution, and compatibility with specific Linux kernel configurations. It serves primarily as a demonstration of an exploit for educational purposes.
