SQL injection is a type of web application attack where an attacker inserts malicious SQL statements into an input field, allowing them to execute unauthorized queries, manipulate databases, and gain access to sensitive information.
• Used by attackers to steal data from databases, including usernames, passwords, and personal information.• Employed in attacks against vulnerable websites or applications that fail to properly sanitize user input.
Attackers exploit vulnerabilities in web applications by inserting malicious SQL code into input fields, which is then executed by the server, allowing unauthorized access to the database.
Consequences include data theft, database manipulation, and potentially full compromise of the affected system.
SQL injection attacks can be prevented by using input validation, parameterized queries, and web application firewalls to filter out malicious SQL code.
