# 🕵️ CVE-2025-55182 — React Vulnerability Analysis

> **Security research & exploitation analysis of a React-based web application vulnerability**
> Conducted as part of MSc Cybersecurity coursework — Central University of Tunis, 2025

---

## 📋 Overview

This repository documents the full security analysis lifecycle of **CVE-2025-55182**, a vulnerability affecting a React-based web application. The project walks through vulnerability discovery, CVSS scoring, proof-of-concept development, threat modeling, and remediation recommendations aligned with the OWASP Top 10.

**Audience:** security researchers, web developers, DevSecOps engineers, penetration testers.

---

## 🎯 Objectives

- Reproduce and document the vulnerability in a controlled lab environment
- Perform static and dynamic security analysis of the target application
- Assess severity using the CVSS v3.1 framework
- Map findings to OWASP Top 10 and MITRE ATT&CK categories
- Propose concrete remediation measures and secure coding practices

---

## 🛠️ Tools & Methodology

| Category | Tools Used |
|---|---|
| **Dynamic Analysis (DAST)** | OWASP ZAP, Burp Suite Community |
| **Static Analysis (SAST)** | Semgrep, ESLint security plugins |
| **Network Inspection** | Wireshark, Chrome DevTools |
| **Fuzzing & PoC** | Custom Python scripts |
| **Scoring** | CVSS v3.1 Calculator (FIRST.org) |
| **Framework Alignment** | OWASP Top 10 2021, MITRE ATT&CK Enterprise |

---

## 🔍 Methodology (STRIDE-inspired Threat Model)

1. **Reconnaissance** — application fingerprinting, dependency enumeration (React version, npm packages)
2. **Attack Surface Mapping** — routes, API endpoints, client-side state exposure
3. **Vulnerability Reproduction** — crafted payloads in an isolated lab VM
4. **Impact Analysis** — confidentiality, integrity, availability assessment
5. **CVSS Scoring** — base score + environmental metrics
6. **Remediation** — secure coding patches, WAF rules, dependency upgrades

---

## 📊 CVSS Assessment (Summary)

| Metric | Value |
|---|---|
| **Attack Vector (AV)** | Network |
| **Attack Complexity (AC)** | Low |
| **Privileges Required (PR)** | None / Low |
| **User Interaction (UI)** | Required |
| **Scope (S)** | Unchanged |
| **Confidentiality Impact (C)** | High |
| **Integrity Impact (I)** | Low / Medium |
| **Availability Impact (A)** | Low |

➡️ **Base Severity: High** *(full calculation details in `/analysis/cvss-score.md`)*

## 🧩 OWASP Top 10 Mapping

The vulnerability analysis touches several categories of the OWASP Top 10 2021:

- **A03:2021 — Injection** — input validation gaps
- **A05:2021 — Security Misconfiguration** — default settings exploitation
- **A06:2021 — Vulnerable and Outdated Components** — dependency chain risk
- **A08:2021 — Software and Data Integrity Failures** — client-side trust boundary

---

## 🛡️ Remediation Recommendations

1. **Input Validation & Sanitization** — strict server-side validation, avoid `dangerouslySetInnerHTML`
2. **Content Security Policy (CSP)** — restrictive directives for script execution
3. **Dependency Management** — automated scanning (Dependabot, Snyk, `npm audit`)
4. **Secure Defaults** — disable development-mode artifacts in production builds
5. **Security Headers** — HSTS, X-Frame-Options, X-Content-Type-Options
6. **Runtime Monitoring** — WAF rules tailored to known payload signatures
