SQL Injection(SQLi), a technique used by attackers to execute malicious SQL Code or extracting sensitive data from platform which could be anything from User lists, customer private data or company sensitive information. This is mainly possible from placing malicious code in SQL Statement in SQL Statements via web page input.
SQL Injection usually happens at the time when the user is asked to input his authorization information, like their username/user id, but in this case, the attacker would put SQL Statement in input field instead of user id which would then run on your database without any suspicion. Simple example of SQL Injection could be as simple as setting password field to ‘password OR 1=1’.
This could be accomplished by searching through source code for all the request calls to external sources and then examining each and every call carefully to be sure that every input field is filtered for checking SQL injections. Developers can be creative in their way by using SQL Parameters for running Queries. SQL parameters are added to an SQL query at its execution time, thus making the system secured from SQL Injections.
