It shows, how an attacker can use an SQL Injection vulnerability to go around application security and authenticate as the administrator. To follow step-by-step how an SQL Injection attack is performed and what serious consequences it may have, see: Exploiting SQL Injection: a Hands-on Example.

You can read more about them in the following articles: Types of SQL Injection (SQLi), Blind SQL Injection: What is it. There are several types of SQL Injection attacks: in-band SQLi (using database errors or UNION commands), blind SQLi, and out-of-band SQLi. In such case, an attacker could use an SQL Injection as the initial vector and then attack the internal network behind a firewall.

In some database servers, you can access the operating system using the database server.

Also, backups may not cover the most recent data. Even if the administrator makes database backups, deletion of data could affect application availability until the database is restored.

You can use SQL to delete records from a database, even drop tables.

For example, in a financial application, an attacker could use SQL Injection to alter balances, void transactions, or transfer money to their account.

SQL also lets you alter data in a database and add new data.

An SQL Injection vulnerability could allow the attacker to gain complete access to all data in a database server.

SQL lets you select and output data from the database.

The impersonated user may be a database administrator with all database privileges.

Attackers can use SQL Injections to find the credentials of other users in the database.

Therefore, a successful SQL Injection attack can have very serious consequences. In some cases, you can also use SQL commands to run operating system commands. Many web applications and websites store all the data in SQL databases. You can use it to access, modify, and delete data. SQL is a query language that was designed to manage data stored in relational databases. After the attacker sends this content, malicious SQL commands are executed in the database. Such content is often called a malicious payload and is the key part of the attack. A web page or web application that has an SQL Injection vulnerability uses such user input directly in an SQL query. To make an SQL Injection attack, an attacker must first find vulnerable user inputs within the web page or web application.

How and Why Is an SQL Injection Attack Performed The OWASP organization (Open Web Application Security Project) lists injections in their OWASP document as the number one threat to web application security. SQL Injection attacks are one of the oldest, most prevalent, and most dangerous web application vulnerabilities. Criminals may use it to gain unauthorized access to your sensitive data: customer information, personal data, trade secrets, intellectual property, and more. They can also use SQL Injection to add, modify, and delete records in the database.Īn SQL Injection vulnerability may affect any website or web application that uses an SQL database such as MySQL, Oracle, SQL Server, or others. They can go around authentication and authorization of a web page or web application and retrieve the content of the entire SQL database. Attackers can use SQL Injection vulnerabilities to bypass application security measures. These statements control a database server behind a web application. SQL Injection (SQLi) is a type of an injection attack that makes it possible to execute malicious SQL statements.
