What occurs during an SQL injection attack?

During an SQL injection attack, malicious SQL code is injected into a database query with the intent of manipulating the database in unauthorized ways. This attack leverages vulnerabilities in an application that allows user-supplied inputs to be included in SQL queries without proper validation and sanitization.

When a web application constructs SQL commands based on user input and fails to properly handle that input, attackers can inject crafted SQL code. This can lead to various malicious outcomes, such as unauthorized access to sensitive data, modification of database records, or even complete control over the database.

For instance, attackers may submit a username and password where the password field is manipulated to execute additional SQL statements that retrieve all user records from the database or alter data without permission. This type of attack can result in severe data breaches, which is why securing applications against SQL injection is a fundamental aspect of cybersecurity practices.

The other options do not accurately describe what occurs during an SQL injection attack. Exposing plain text passwords can be one consequence of data breaches, but it is not a direct result of SQL injection. Security patches are typically a defense mechanism against various attacks, including SQL injection, rather than an event that occurs during an attack. Losing access to accounts by authenticated users does not specifically relate to SQL injection
