In an SQL injection attack, an application interprets data submitted by a cyber criminal as a command and responds with sensitive details. What Are the Risks Associated with SQL Injection? For any of these applications, it becomes essential to perform vulnerability testing to ensure there are no loopholes for executing SQL injection. Several websites and web applications store data in SQL databases. This exploit of security aims at gaining access to the unauthorized data of a website or application. Attackers use malicious SQL statements in the input box, and in response, the database presents sensitive information. SQL statements are used to retrieve and update data in the database. SQL serves as the way of communication to the database. Then, leveraging malicious code, a hacker can acquire a response that provides a clear idea about the database construction and thereby access to all the information in the database. The hacker can execute a specifically crafted SQL command as a malicious cyber intrusion. When an application or webpage contains a SQL injection vulnerability, it uses user input in the form of an SQL query directly. To perform an SQL injection attack, an attacker must locate a vulnerable input in a web application or webpage. Why Do Attackers Perform an SQL Injection Attack? One recent report lists it as the third most common serious vulnerabilities.
SQL injection attacks are one of the most prevalent among OWASP Top 10 vulnerabilities, and one of the oldest application vulnerabilities. Hackers use SQL injection attacks to access sensitive business or personally identifiable information (PII), which ultimately increases sensitive data exposure. If a web application or website uses SQL databases like Oracle, SQL Server, or MySQL, it is vulnerable to an SQL injection attack.
A successful SQL injection exploit can read sensitive data from the database, modify database data (viz., insert, update, or delete), execute administrative operations on the database, recover the content of a file present in the database management system, and even issue commands to the operating system in some instances. SQL commands are injected into data-plane input that affect the execution of predefined SQL commands. An SQL injection attack consists of an insertion or injection of a SQL query via the input data from the client to the application.
