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.
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.
