[X] Modify src/main/java/org/owasp/webgoat/lessons/sql_injection/introduction/SqlInjectionLesson10.java ✓ https://github.com/qdw1987/WebGoat/commit/70ee60bfb32c7bb76b2a6daf106c73f1ad1b199c Edit
Modify src/main/java/org/owasp/webgoat/lessons/sql_injection/introduction/SqlInjectionLesson10.java with contents:
• Locate the method that handles the POST request and performs the SQL query. This method will likely have a @PostMapping annotation and a parameter that receives user input.
• Identify the part of the method where the SQL query is constructed. This will likely involve concatenating a SQL string with the user input.
• Replace the direct concatenation of user input into the SQL string with a parameterized query. This can be done using a PreparedStatement, which allows you to set parameters in the SQL query that will be automatically sanitized by the JDBC driver.
• For each parameter in the SQL query, call the setString method (or the appropriate set method for the parameter's data type) on the PreparedStatement, passing the index of the parameter and the user input.
• Execute the query using the executeQuery method on the PreparedStatement, and handle the results as before.
• Ensure that all database resources, such as ResultSet and PreparedStatement, are properly closed in a finally block to prevent resource leaks.
