Online SQL Injection Tool for HTTP GET method Detail

Scan your web apps for SQLi vulnerabilities with this tool for HTTP GET method.

Online SQL Injection Tool for HTTP GET method

With free and online SQL injection scanning tool, you can scan SQL Injection vulnerabilities for query parameters sent with the HTTP GET method. Furthermore, you can either export this scan's result as PDF or watch all scanning processes as video.

For example, this SQL Injection tool parses param1 and param2 parameters and test for sql vulnerability for a url such:

Due to ethical concerns, you should verify that your website belongs to the site when checking for this vulnerability.

What is SQL Injection Vulnerability?

In dynamic pages in web applications, the information presented to the user is often served by reading from databases. Reading from the database is performed within database-specific rules. Databases in which data are stored relationally in accordance with predetermined templates (table structures) are called relational databases. Structured Query Language (SQL) is a programming language for managing data in relational databases.

In web applications, user-received values can be included in SQL queries in some cases. The queries created by using the parameters received from the user in statements are called dynamic SQL queries. For example, in order to search, the value to be searched must be obtained from the user. Similarly, in order to paginate, it is not possible to read the relevant data from the database without obtaining the number of the page that the user wants to view. So statements are used in these types of queries called dynamic.

The attacks by interfering with dynamic SQL statements running on the target system are called SQL Injection attacks, and the resulting vulnerability itself is called SQL Injection Vulnerability.

By triggering this vulnerability, cyber attackers can perform many different malicious operations, from gaining information about the database, accessing database administrator passwords, deleting and capturing data, running custom SQL statements in the database, and even running commands in the operating system by interfering with SQL queries.

SQL Injection vulnerabilities are the vulnerabilities that occur when the inputs from the user are used in SQL queries without filtering them correctly. The vulnerabilities are divided into sub-categories according to the triggering method. We have listed all the categories we could find by scanning the academic literature below:


Some of these categories are actually used for vulnerabilities of the same type. 6 of them are categories included in open-source software called SQLmap, which we also use in our SQL injection scanner tool.


Let's take a look at these.

In blind SQL injection vulnerabilities, attackers cannot directly interfere with any data on the target system. Instead, attackers exploit this type of vulnerability by delaying the response from the server (time-based), or by converting some behaviors in the returned response into a state (true/false).


Figure Blind SQL Injection (Time Based Example)

Union is a special expression that combines two different queries to return a single answer. In Union-based SQL Injection attacks, real SQL query and the SQL query sent by the attacker combined (like select col1, col2 from table union select col1, col2 from other_table). Therefore database run both valid and malicious query and return the answer.

In the Stacked-based (piggy-backed) SQL Injection vulnerability, the attacker sends an independent query to the target system, allowing its own query to run after the first query that exists on the target system (like select * from table;select password from users;) . Such vulnerabilities may not work in every database and web application. For example, the sequential execution of more than one SQL query at a time is turned off by default in some frameworks.

In error-based SQL Injection attacks, the attacker sends the payload to the target system that will cause errors in database queries. The resulting error leaves a trace in the body or headers in the returned response. By looking at this trace, the attacker can collect the necessary information on the target system.


Figure Error Based SQL Injection

In the type of inline queries, SQL Injection vulnerabilities, as the name suggests, are vulnerabilities where SQL queries are manipulated using inline queries. The attacker forces the system to work in its own interests by injecting the SQL queries it uses into real SQL queries.

If there is a connection you suspect, you can use this tool that tests the SQL Injection vulnerability in the GET parameters for your web application.

Some Advice for Common Problems

You can apply the following methods to avoid SQL Injection vulnerability.

  • Where SQL queries are made by taking input from the user (for dynamic queries), parameter binding (also known as prepared statements) should be applied. Stored procedures can be preferred.
  • User inputs should never be trusted, all inputs should be processed after filtering. While filtering, instead of blocking individual characters (black-listing), a certain character string should be allowed, and the remaining characters should be blocked (white-listing).
  • While making a database connection, the principle of least privileges should be applied. The connection should be provided by giving limited access to the necessary places. No connection to the database should be made with authorized users such as "root", "SA".
  • Critical data should be encrypted in the database, not in plain text.
  • A custom error page should be created and displayed at the time of error so that the database information is not exposed during an exception that may occur in the web application.
