How to fix - SQL Injection

SQL injection is a type of vulnerability that occurs when an attacker can insert malicious SQL code into a web application's query. This can allow the attacker to view, modify or delete data in the database, potentially giving them access to sensitive information. There are a few ways to fix SQL injection:

  • Use prepared statements or parameterized queries. These methods allow you to separate the data from the query, so that user input is not directly inserted into the query. This means that even if an attacker enters malicious SQL code, it will not be executed as part of the query.

  • Use an Object-Relational Mapping (ORM) library. ORMs are a way to interact with databases using objects, rather than writing raw SQL. ORMs take care of parameterizing queries and escaping input, so you don't have to do it manually.

  • Use input validation. This is a technique for validating user input before it is passed to the query. This can include checking the input against a whitelist of allowed values, or ensuring that it conforms to a certain pattern.

It is important to note that it is a good practice to use a combination of the above methods for best results, and to keep the software and libraries used by the application up-to-date to prevent SQL injection vulnerabilities.
