# Vulnerability Exploitation β€” MegaQuagga Penetration Test Report

**Analyst:** Samuel Weiss
**Organization:** 0x2A Security
**Date:** April 20, 2026
**Client:** MegaQuagga Publishing
**Target:** www.megaquagga.local
**Classification:** CONFIDENTIAL

---

## Overview

This project documents a **structured penetration test** conducted against the MegaQuagga Publishing web environment. The engagement confirmed five exploitable vulnerabilities, two of which were chained to achieve unauthenticated Remote Code Execution (RCE) and establish a persistent Meterpreter session on the target host.

## Scope

**In-Scope:**
- Primary target: `www.megaquagga.local`
- Associated subdomains bound to the megaquagga.local domain
- Web application stack: WordPress CMS, Apache 2.4.38, PHP runtime
- Active WordPress plugins

**Out-of-Scope / Prohibited:**
- Third-party or shared hosting systems
- Indiscriminate brute-force attacks
- DoS/DDoS without explicit written approval
- Data destruction, alteration, or exfiltration
- Social engineering or physical security testing

## Six-Phase Methodology

| Phase | Activity |
|-------|----------|
| Phase 0 β€” Pre-Engagement | Formal scoping, rules of engagement, mutual NDA |
| Phase 1 β€” Reconnaissance | ICMP host discovery; HTTP on TCP/80 confirmed as primary entry vector |
| Phase 2 β€” Scanning | `db_nmap -A` via Metasploit; OS detection, service fingerprinting, NSE scripts |
| Phase 3 β€” Vulnerability Identification | Plugin version cross-reference against NVD, WPScan DB, and Exploit-DB |
| Phase 4 β€” Exploitation | CVE chaining for unauthenticated RCE and persistent Meterpreter session |
| Phase 5 β€” Post-Exploitation | Host profiling, access confirmation, blast radius documentation |

## Findings

### Critical Vulnerabilities

#### F-01 β€” Unauthenticated RCE via social-warfare Plugin (CVE-2019-9978)
- **CVSS:** 9.8 Critical
- **Plugin Version:** social-warfare v3.5.2 (patched in v3.5.3)
- **Description:** Failure to sanitize the `swp_url` POST parameter before passing it to `eval()` server-side. An unauthenticated attacker can execute arbitrary PHP code with no credentials required.
- **Impact:** Full unauthenticated RCE as `www-data`; read access to `wp-config.php` (database credentials), all hosted files, and a network pivot point.

#### F-02 β€” Reverse Shell Delivery & Persistence via CVE-2023-4842
- **CVSS:** 9.8 Critical
- **Description:** Chained with F-01 to deliver a reverse shell payload, establishing an outbound TCP connection bypassing inbound firewall rules.
- **Impact:** Stable, persistent Meterpreter session. Supports file system access, process migration, and credential harvesting. Survives brief network interruptions.

### Additional Vulnerabilities (Medium–High)
- Absent HTTPS β€” unencrypted HTTP-only service on TCP/80
- Exposed XML-RPC interface β€” credential enumeration and brute-force risk
- Default WordPress file exposure and username disclosure via author pages

## Attack Chain Summary

```
[Attacker] β†’ CVE-2019-9978 (swp_url injection) 
           β†’ PHP payload executed server-side 
           β†’ CVE-2023-4842 (reverse shell delivery) 
           β†’ Meterpreter session established as www-data 
           β†’ Read access to wp-config.php, all hosted files, potential lateral movement
```

**Confirmed Access Level:** `www-data` web server user on megaquagga-web (Ubuntu x86_64)

## Remediation Recommendations

| Priority | Recommendation | Timeline |
|----------|---------------|----------|
| Critical β€” Immediate | Update social-warfare to v3.5.3+; remove if unused | 48–72 hours |
| Critical β€” Immediate | Audit and remove galactic-file-uploader if not business-critical | 48–72 hours |
| Short-Term | Deploy TLS and enforce HTTPS; disable HTTP on port 80 | 30 days |
| Short-Term | Disable or restrict the XML-RPC interface | 30 days |
| Medium-Term | Implement a formal WordPress patch management policy with monthly audits | 90 days |
