So whenever the above SQL query returns a TRUE value, then login is successful and when it returns a FALSE value then login is unsuccessful. If any of the inserted fields are not matched with that of in the users’ table, then no row is returned.

When this query is executed, if there is a username “ San_123” stored in the users’ table having a corresponding password “ 1234d678“, then this particular row is returned. This query simply implies to fetch any number of rows that match the condition mentioned after the where clause. This will generate a query to the database such as select * from users where username=’San_123′ and password=’1234d678′ Suppose the attacker enters the login credentials of user San_123. Even if any of the entered value is wrong then login access is denied.Ĭonsider the web application that has the following database of username and password. If the entered data is matched with the data stored in the database then only the login is succeeded. It will match the users entered data with the data stored in the database of the application.

While you are attempting to login to the application when you enter your username and password it will generate a query that is passed to the database. Usernames and passwords of all the users are stored in the database of the web application. For this, you have to enter your assigned username and the corresponding password. To use this web application you have to first login to the application.

So we can simply say it as a technique in which code is injected in SQL queries to execute malicious statements on the database.

Now as the query is manipulated it gets executed which results in spitting the output that attacker wants instead of the one that should be ideally returned by that SQL query otherwise.

So first the attacker frames certain SQL statements to manipulate the query generated by the web application by injecting some malicious strings in it. Therefore, it will perform certain actions which it isn’t supposed to do. Above all, This is what expected to happen.īut when the attacker uses SQL Injection, the query that is generated to be executed on the database is manipulated. In this case database query is generated on the web application which is sent to the database and executed there to return the desired output to the web application. It is taking input from the user and storing data on the database or fetching data from the database to display it to the user. “SQL Injection is a type of attack in which an attacker can access the database of any web application by manipulating the queries with the inputs that cause displaying of information that wasn’t intended to be displayed.” What is SQL Injection?Ĭonsider a web application using a database. If you have a web application that uses a database then you must have to look at what exactly SQL injection is and how it works that will cause your application to perform beyond your controls. Moreover, it is there in the OWASP top 10 vulnerabilities since the beginning. It is the most common and most used web-based attack. You have to provide the best security to the database for the sake of service continuity but imagine even after providing the best network protocols to the database, any attacker is just able to manipulate the database even without entering the internal network of your organization. When you are running a web application, so what do you think is the most important thing for you? Can you guess it? It’s none other than the database.
