# CVE-2016-15042 – WordPress Frontend File Manager & N‑Media Post Front‑end Form Unauthenticated File Upload (PoC Lab)

Fully reproducible, Dockerized lab to validate and demonstrate CVE-2016-15042:

- Frontend File Manager (`nmedia-user-file-uploader`) v3.7 (vulnerable < 4.0)
- N‑Media Post Front‑end Form (`wp-post-frontend`) v1.0 (vulnerable < 1.1)

This repo provides a one-command setup, verification steps with Nuclei, and artifacts for reviewers. Keywords: WordPress, CVE-2016-15042, unauthenticated file upload, arbitrary file upload, PoC, security lab, Docker.

## Requirements

- Docker + Docker Compose plugin
- curl
- Nuclei (optional, for verification)

## Quick start

```bash
./scripts/setup.sh
```

Once finished:

- WordPress: <http://localhost:8090>
- Admin: admin / admin
- Public user: publicuser / publicpass

## Verify the vulnerability with Nuclei (debug enabled)

Option A: Download the template locally into this lab folder and run it.

```bash
curl -sL "https://raw.githubusercontent.com/projectdiscovery/nuclei-templates/refs/heads/main/http/cves/2016/CVE-2016-15042.yaml" -o ./CVE-2016-15042.yaml
nuclei -t ./CVE-2016-15042.yaml -u http://localhost:8090 -debug -vv \
  | tee ./debug/CVE-2016-15042-debug.txt
```

Option B: If you have the templates repo locally, run the template by path:

```bash
nuclei -t /path/to/nuclei-templates/http/cves/2016/CVE-2016-15042.yaml -u http://localhost:8090 -debug -vv \
  | tee ./debug/CVE-2016-15042-debug.txt
```

The debug output file is stored at `./debug/CVE-2016-15042-debug.txt` for reviewers.

## What this lab does

- Boots a clean WordPress with the two vulnerable plugins
- Configures guest uploads for Frontend File Manager for reliable unauthenticated testing
- Exposes WordPress on `localhost:8090`

## Notes

- If ports or credentials collide in your setup, edit `docker-compose.yml` and re-run the script.
- Artifacts are kept under `./debug/` for easy PR review.
