SQL Injection Demonstration 💉

This is a Node.js/Express.js based application with SQL Server Database, vulnerable to SQLi to demonstrate the SQL Injection attack.

Getting Started 🔰

1. Installation ⬇

  • Clone this repo

    $ git clone git@github.com:AbdulMoizAli/SQL-Injection-Demo.git

$ cd SQL-Injection-Demo

  • Install the dependencies

    $ npm install

2. Configuration 🛠

  • Connect to the local instance of SQL Server and Execute the init.sql script to create and populate the database and tables. You can use SSMS or Azure Data Studio to execute the script.

  • Rename the .env.sample file to .env and configure the node environment variables. Use your SQL Server credentials in the .env file.

    DB_USER=Your SQL Server login name
DB_PASSWORD=Your SQL Server login password
DB_SERVER=localhost
DB_NAME=Moviedb

Usage ⚙

1. Start the server 🖥

$ npm run dev

Use SQL statements from the inject.sql script to demonstrate the SQLi attack. inject.sql contains the common flow and 5 UNION based SQL statements that are typically used to attack and extract information from the database.

2. Example 👇

Injecting the following SQL Statement in the user input would retrieve the users information, such as user's Email and Password Hash. Make sure to include a single quote at the start and 2 hyphens at the end of the statement.

' UNION
  SELECT Id, Email, PasswordHash, [Type], '2020-11-20', 1, 3.14, 'foo'
  FROM Account; --
