Custom API Vulnerability Scanner: Build a custom vulnerability scanner tailored to detecting API-specific issues. This tool could:

first Overview:

The Custom API Vulnerability Scanner is a tool designed to identify security vulnerabilities in APIs. It includes checks for common vulnerabilities such as SQL Injection, XSS, and sensitive data exposure. It also integrates with Swagger/OpenAPI documentation for dynamic endpoint testing, and includes checks for token leakage and rate limiting. The tool can be used via a command-line interface (CLI) or a simple web-based UI. Features

Vulnerability Detection: Checks for SQL Injection, XSS, and sensitive data exposure.
Token Leakage: Detects potential hard-coded or exposed tokens.
Rate Limiting: Identifies rate-limiting mechanisms and thresholds.
Swagger/OpenAPI Integration: Parses OpenAPI specifications to dynamically test endpoints.
Web Interface: Provides a simple web-based UI for interaction (Flask-based).

Prerequisites

Python 3.7 or higher
requests library
Flask library (for the web interface)
pydantic library

Installation

Clone the Repository:

bash

git clone https://github.com/your-repo/api-vulnerability-scanner.git cd api-vulnerability-scanner

Install Dependencies:

It is recommended to use a virtual environment.

bash

python -m venv venv
source venv/bin/activate  # On Windows use `venv\Scripts\activate`
pip install -r requirements.txt

CLI Usage Basic Usage

The CLI allows you to scan an API by providing the URL of the OpenAPI specification.

Run the Scanner:

bash

python scanner.py --url <API_DOCUMENTATION_URL>

Replace <API_DOCUMENTATION_URL> with the URL of your OpenAPI specification.

Example

To scan an API with the OpenAPI documentation available at https://api.example.com/swagger.json, run:

bash

python scanner.py --url https://api.example.com/swagger.json

CLI Options

--url: The URL of the OpenAPI documentation. This option is required.

Step-by-Step CLI Instructions

Ensure Dependencies are Installed:

Before running the scanner, make sure all required libraries are installed. Follow the Installation instructions.

Prepare OpenAPI Documentation:

Ensure that your API has an OpenAPI specification available at a publicly accessible URL.

Run the Scanner:

Execute the CLI command with the appropriate URL to start scanning:

bash

python scanner.py --url <YOUR_OPENAPI_SPEC_URL>

Review Results:

After the scan completes, review the output for identified vulnerabilities and issues.

Web Interface Running the Web Interface

To use the web-based UI, start the Flask application:

bash

python web_interface.py

The web interface will be available at http://127.0.0.1:5000. Using the Web Interface

Open the Web Interface:

Navigate to http://127.0.0.1:5000 in your web browser.

Submit API Documentation URL:

Enter the URL of the OpenAPI specification in the provided form.

Start Scanning:

Click the submit button to start the scan. The results will be displayed on the page.

Testing

To ensure the scanner functions correctly, run the test suite using pytest:

bash

pytest
