=====================================
The SQL injection attack consists of insertion or “injection” of a SQL query via
the input-login data from the client to the application. The successful SQL injection
exploit can read sensitive data from the database, modify database data
(Insert/Update/Delete), execute administration operations on the database
(such as shutdown the DBMS), recover the content of a given file present on the DBMS file system.
