Cloning the Arsenal: SQLiScanner and Sqlmap

Every serious operator needs their tools. For automating SQL injection, the bedrock of exploration often lies in Git repositories. Professional operations demand efficiency, and manual downloads are for amateurs. First, acquire SQLiScanner. Think of this as your command console. The `depth 1` flag is crucial for a lean checkout, hoarding bandwidth and disk space – essential when you’re operating in stealth. 
git clone https://github.com/0xbug/SQLiScanner.git --depth 1
Simultaneously, you'll need the engine: `sqlmap`. This isn't just a scanner; it's a precision instrument for detecting and exploiting SQL injection flaws. Cloning it with `depth 1` ensures you have the latest iteration without the baggage of historical commits. 
git clone https://github.com/sqlmapproject/sqlmap.git --depth 1
Securing these tools is your first line of defense, ensuring you’re not downloading compromised versions. For serious bug bounty hunters targeting high-value programs, investing in these foundational tools and understanding their intricacies is non-negotiable. Platforms like HackerOne and Bugcrowd often feature challenges that directly test your proficiency with such automated scanners.

Setting the Stage: Python Environment and Dependencies

For SQLiScanner to perform its digital alchemy, it thrives in the structured environment of Python 3.x. This isn't a negotiable point; the ecosystem is built on it. Linux and macOS are the preferred battlegrounds. Trying to run this on a misconfigured Windows box is a rookie mistake that costs time and sanity. Your next step is to isolate dependencies. A virtual environment, or `venv`, is your sandbox. It prevents conflicts and ensures that your `pip` installs don't wreak havoc across your system. Navigate into the downloaded SQLiScanner directory. Prepare your environment: 
cd SQLiScanner/
virtualenv --python=/usr/local/bin/python3.5 venv
source venv/bin/activate
With your environment primed, install the necessary components. The `requirements.txt` file is your manifest, detailing everything needed for the operation. 
pip install -r requirements.txt
This step is where many operations stall. Ensure your Python installation is correct and accessible. If you’re serious about web application security, mastering Python environments is as critical as understanding network protocols. For advanced users, consider exploring tools that streamline Python environment management, such as `pyenv`.

Configuring the Backend: Databases and Email Integration

SQLiScanner, being a Django application, relies on a robust backend. The default configuration might be a starting point, but a real operation requires customization. The `DATABASES` setting in `SQLiScanner/settings.py` is your anchor. While it defaults to PostgreSQL, you'll need to input your specific database credentials. Leaving these blank is a cybersecurity faux pas that could lead to unintended access or configuration errors. 
# Setting DATABASES in SQLiScanner/settings.py:85
DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': '',  # Your database name
        'USER': '',  # Your database user
        'PASSWORD': '',  # Your database password
        'HOST': '127.0.0.1',
        'PORT': '5432',
    }
}
For automated scanning, receiving notifications is key. The `SendEmail` section allows SQLiScanner to alert you upon completion or discovery. Configure your SMTP server details, or risk missing critical findings. 
# Setting Email in SQLiScanner/settings.py:158
EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_USE_TLS = False  # Set to True if your SMTP server requires TLS
EMAIL_HOST = ''        # Your SMTP host, e.g., 'smtp.gmail.com'
EMAIL_PORT = 25        # Your SMTP port, e.g., 587 for TLS
EMAIL_HOST_USER = ''   # Your email address for sending notifications
EMAIL_HOST_PASSWORD = '' # Your email password
DEFAULT_FROM_EMAIL = '' # Default sender email address
Properly configuring these settings ensures that your scans are logged and reported effectively. If you're not receiving emails, double-check your credentials and server settings – a common oversight in automated workflows.

Orchestrating the Attack: Redis, Celery, and the API

To handle scans asynchronously and efficiently, SQLiScanner leverages Celery and Redis. Redis acts as the message broker, a high-speed queue for task distribution, while Celery workers process these tasks in the background. This separation ensures that the main Django application remains responsive, even under heavy load. When you initiate a scan, the request is placed in the Redis queue, and a Celery worker picks it up. The `SqlScanTask` class within `scanner/tasks.py` is the core logic for interacting with the `sqlmap` API. 
# scanner/tasks.py:14
class SqlScanTask(object):
    def __init__(self, sqli_obj):
        self.api_url = "http://127.0.0.1:8775"  # Default sqlmap API endpoint
        self.mail_from = ""                     # Sender for email notifications
        self.mail_to = [""]                     # Recipient(s) for email notifications
Before launching the worker, you must ensure Redis is running on `127.0.0.1:6379` by default. This distributed architecture is crucial for scalability. If you're managing large-scale penetration tests or bug bounty hunting across multiple targets, this setup is infinitely more robust than a single-threaded approach. Understanding Celery and Redis goes beyond just running a tool; it’s about understanding system architecture for distributed tasks.

Launching the Operation: Running SQLiScanner

With all components configured, it’s time to bring the system online. This phase requires precision and understanding of the operational sequence. First, ensure your Django project is ready for deployment by running migrations. This sets up the necessary database schema. 
python manage.py makemigrations scanner
python manage.py migrate
Next, establish your superuser credentials. This grants you access to the Django admin panel, a crucial interface for managing the scanner and viewing results. 
python manage.py createsuperuser
Now, initiate the core services in the correct order: 1. **Start Redis Server**: The communication hub. 
redis-server
2. **Start Sqlmap API**: This exposes `sqlmap`'s functionality for programmatic access. 
python sqlmapapi.py -s -p 8775
The `-s` flag signifies server mode, and `-p 8775` sets the listening port. 3. **Start Celery Worker**: To process scan tasks. 
python manage.py celery worker --loglevel=info
The `--loglevel=info` provides verbose output, essential for debugging. 4. **Run Django Development Server**: To power the web interface. 
python manage.py runserver
This sequence ensures all dependencies are met and services are initiated in an order that prevents startup failures. For production environments, consider using tools like `systemd` or `supervisor` to manage these services robustly.

Practical Workshop: Automating Your First SQLi Scan

This section will guide you through initiating a basic scan using SQLiScanner once your environment is set up and all services are running.
  1. Access the Interface: Open your web browser and navigate to http://127.0.0.1:8000/.
  2. Login: Use the superuser credentials you created earlier to log in.
  3. Initiate a Scan: Locate the section for creating new scan tasks. You will typically need to provide:
    • Target URL: The full URL of the application you want to scan (e.g., http://testphp.vulnweb.com/login.php).
    • Scan Type: Select the appropriate type, often a basic SQL injection scan.
    • Optional Parameters: Depending on the interface, you might set cookies, user-agent strings, or other `sqlmap` specific options.
  4. Monitor the Scan: The dashboard should show a new task being added to the queue. You can monitor the Celery worker's output in your terminal for real-time progress. The SQLiScanner interface will also update with the scan's status.
  5. Review Results: Once the scan is complete, the results will be displayed in the web interface. This typically includes details of detected SQL injection vulnerabilities, the payloads used, and potentially database information. For deeper analysis, you can always refer to the raw `sqlmap` logs or output.
Remember, always perform scans on systems you have explicit permission to test. Unauthorized scanning is unethical and illegal.
