SQL injection refers to a technique where an attacker can execute malicious SQL statements that control a web application�s database. SQL injection vulnerabilities can attack any website or application that makes use of the database server. This vulnerability is one of the oldest and most dangerous of all the web application attack. In SQL injection attack an attacker tries to gain unauthorized access on the database which allows an attacker to spoof the identity, destroys the data present on the system, and changes the records present on the database.
