Learn Basic SQL Injection

SQL Injection (SQLi) represents a severe web security vulnerability that enables attackers to manipulate an application’s database queries. Through these manipulations, attackers can access, alter, or delete data, perform administrative tasks, or even gain full control over the database server.

This vulnerabilities arise primarily due to poor handling of user input by applications. When developers insert user-supplied data directly into SQL queries without proper sanitization or parameterization, it creates opportunities for exploitation.

A successful SQL injection attack can lead to unauthorized access to sensitive data, including:

In some cases, attackers can install a persistent backdoor into an organization’s systems, also can escalate a SQL injection attack to compromise the underlying server or other back-end infrastructure. It can also enable them to perform denial-of-service attacks.
