As you can see in the snippet above, whatever the user puts in the search field, if not found in the database, will be sent back to the user in an unchanged form. What that means is that if an attacker puts JavaScript code instead of the product name in your search bar, the same JavaScript code will be executed. To validate the User input!You can use validator js or xss-filters for that.
We talked about automatic vulnerability scanning before, but you can go one step further and catch common security vulnerabilities even while writing the code. How? By using linter plugins like eslint-plugin-security. A security linter will notify you every time you use unsafe code practices (for example using eval or non-literal regex expressions).
Writing secure code from the beginning will help, but it won’t make your application bulletproof if you end up storing plain text secrets in your config files. This practice is unacceptable even if you store the code in a private repository. Importing secrets from environment variables is the first step, but it’s not a perfect solution either. To be more confident that your secrets aren’t easily readable, use secret management solutions like Vault. Whenever using Vault isn’t possible, encrypt your secrets when you store them and be sure to rotate them regularly. Many CI/CD solutions allow you to securely store secrets and securely deploy them.
To prevent SQL Injection attacks to sanitize input data. You can either validate every single input or validate using parameter binding. Parameter binding is mostly used by developers as it offers efficiency and security. If you are using a popular ORM such as sequelize, hibernate, etc then they already provide the functions to validate and sanitize your data. If you are using database modules other than ORM such as mysql for Node or Mongoose, you can use the escaping methods provided by the module. Let's learn by example. The codebase shown below is using mysql module for Node.
