描述

FreePBX CVE-2025-57819 lab (Docker) + Nuclei POC for unauth SQLi (time-based).

介绍

# (Work in Progress) FreePBX CVE-2025-57819 Lab - Unauth SQLi → RCE Chain (Nuclei POC)

Spin up a reproducible FreePBX 15 lab (Docker) to validate CVE-2025-57819 — a critical unauthenticated SQL injection in `userman` AJAX endpoints that can be chained to RCE. Includes a working Nuclei template (behavior-based, not version checks) and a debug-friendly test harness.

## Highlights

- Unauthenticated time-based SQLi POC (SLEEP) on `userman` endpoints
- Minimal Docker Compose (MariaDB + FreePBX 15)
- Nuclei POC template with `-debug` validation
- Make targets for quick bring-up and test

## Quick Start

Prereqs: Docker + Docker Compose. For Nuclei, either install locally or use the official container (used by default).

```bash
# bring up the lab
make up

# wait until FreePBX is responding
make wait

# quick timing check (expect ~6s delay on injected request)
make check

# run nuclei POC with debug (via Docker)
make test-nuclei

# all-in-one
make test
```

If you have Nuclei installed locally, you can run:

```bash
nuclei -u http://127.0.0.1:8080 -t templates/CVE-2025-57819.yaml -vv -debug -debug-req -debug-resp
```

## How It Works

- Vulnerable endpoints:
  - `/admin/ajax.php?module=userman&command=checkPasswordReminder`
  - `/ucp/ajax.php?module=userman&command=checkPasswordReminder`
- The template sends a baseline POST and a SLEEP-injected POST. A ≥5s delay on the injected request indicates likely SQLi.
- This is a detection-only POC (non-destructive). Do not attempt file writes in shared environments.
