Structured query language injection is a process through which one can intrude the database of a software application (mostly in web applications) through the application’s user interface. By adding or editing strings to the SQL query, injection is performed, thereby hacking sensitive user details. The hackers can even create humongous problems by dropping the entire data in the database. The hacker deeds all the security susceptibilities in the injection. When the user input is not captured sturdily and executed unexpectedly, injection could happen.
