How to Check For SQL Injection Easily

In this blog post, we will learn how to check for SQL Injection easily using an online and free tool.

Before we get into how to check SQL Injection vulnerability online, let's cover some elementary topics.

Summary For SQL Injections

If you need a refresher on SQL injections or are learning about them for the first time, this information will help give you a complete understanding of the topic.

What is SQL Injection?

SQL stands for Structured Query Language. It is a standard language for accessing databases.

SQL injection is a type of attack where the attacker inserts malicious SQL code into an input field in order to execute a malicious query on the database.

This can be done by inserting a SQL code into an input field that is used in a SQL query. If the input field is not properly sanitized, then the attacker can execute a malicious query on the database.

Some SQL Injection Types

The five types of SQL injections we want to mention are:

1. Blind SQL Injection: In this type of attack, the attacker does not know the structure of the database. The attacker can only insert a SQL code into an input field and then see the response from the server.

2. Error-based SQL Injection: In this type of attack, the attacker can easily learn the structure of the database. The attacker can insert a SQL code into an input field and then see the error message from the server.

3. Union-based SQL Injection: The attacker uses the UNION operator to combine the results of two or more SQL queries.

4. Time-based SQL Injection: The attacker can use some functions to make the server wait for a certain amount of time.

5. Out-of-band SQL: The attacker can use some functions to make the server communicate with another system.

Risk of SQL Injection Attacks

SQL injection attacks can be very dangerous. The attacker can insert a SQL code that can delete all the data in the database. The attacker can also insert a SQL code that can change the data in the database or get sensitive information from the database.

Also, depending on vulnerability types attackers can upload a file, read a file from the file system or run commands at operating system level.

How to Check For SQL Injection Easily

We will use one of our free and online tools named Online Generic SQL Injection Vulnerability Scanner

Our SQL Injection scanner can quickly check for SQL Injection vulnerability at your app *. Here are the 3 simple stages you may take.

Let's assume you have a website named securityforeveryone.com. And you wish to scan some of its pages for SQL Injection vulnerabilities using an online tool.

1. Using Fast Scanner

The simple and easiest way is using Fast Scan features only if you want to scan a GET parameter.

For example, if you have a web page such as https://securityforeveryone.com/test?id=3 you can write it to URL area and click start scan. Our scanner will start in seconds and check SQL Injection vulnerability for ' id ' parameter.

2. Using HTML form parser

Use an HTML form parser to scan for SQL Injection vulnerability for forms in your HTML code.

Let's assume you have form in your contact page.

Write https://securityforeveryone.com/contact in the area and click analyze button.

Then, select the form you need to scan. That's all.

3. Expert Mode

Use this mode to scan input that can't be accessed via a webpage.

Another scenario to use this feature is if you need to generate a custom request for scanning.

Click "Open Export Mode" button.

Select the necessary request information you want to check for SQL Injection online.

Click "Start scan" button.

Scan may take 10 minutes depending on your web app.

If there is a SQL Injection vulnerability on your page, you will see a report similar to the one below:
