- The code has to be injected in such a way that the SQL statement should generate a valid result upon execution. If the executed SQL query has errors in the syntax, it won't featch a valid result. So filling in random SQL commands and submitting the form will not always result in succesfull authentication.
- You can find more on this topic on the OWASP prevention Cheat Sheet. SQL injection common filters bypass. To prevent SQL injection, developers use common filters to check user input. Unfortunately, they can be bypassed. Whether you are As a developer or an ethical hacker, you should be aware of them.
- SQL Injection Prevention Cheat Sheet; JPA Symptom. Injection of this type occur when the application use untrusted user input to build a JPA query using a String and execute it. It's quite similar to SQL injection but here the altered language is not SQL but JPA QL. Use Java Persistence Query Language Query Parameterization in order to prevent injection.

SQL Injection is one of the most dangerous web vulnerabilities. So much so that it's the #1 item in the OWASP Top 10. It represents a serious threat because SQL Injection allows evil attacker code to change the structure of a web application's SQL statement in a way that can steal data, modify data, or potentially facilitate command injection to the underlying OS. This cheat sheet is a derivative work of the SQL Injection Prevention Cheat Sheet.

SQL Injection is best prevented through the use of parameterized queries. The following chart demonstrates, with real-world code samples, how to build parameterized queries in most of the common web languages. The purpose of these code samples is to demonstrate to the web developer how to avoid SQL Injection when building database queries within a web application.

Stored Procedure Examples
The SQL you write in your web application isn't the only place that SQL injection vulnerabilities can be introduced. If you are using Stored Procedures, and you are dynamically constructing SQL inside them, you can also introduce SQL injection vulnerabilities. To ensure this dynamic SQL is secure, you can parameterize this dynamic SQL too using bind variables. Here are some examples of using bind variables in stored procedures in different databases:
| Language - Library | Parameterized Query |
|---|---|
| Oracle - PL/SQL | Normal Stored Procedure - no dynamic SQL being created. Parameters passed in to stored procedures are naturally bound to their location within the query without anything special being required. |
| Oracle - PL/SQL | Stored Procedure Using Bind Variables in SQL Run with EXECUTE. Bind variables are used to tell the database that the inputs to this dynamic SQL are 'data' and not possibly code. |
| SQL Server- Transact-SQL | Normal Stored Procedure - no dynamic SQL being created. Parameters passed in to stored procedures are naturally bound to their location within the query without anything special being required. |
| SQL Server- Transact-SQL | Stored Procedure Using Bind Variables in SQL Run with EXEC. Bind variables are used to tell the database that the inputs to this dynamic SQL are 'data' and not possibly code. |
