This pull request includes several security improvements and code refactoring in the project. The most important changes include adding CSRF protection, replacing hardcoded secrets with environment variables, removing vulnerable scripts, and using parameterized queries to prevent SQL injection.

Security Improvements:

  • app.js: Added CSRF protection by including the csurf middleware and updated session secret to use an environment variable. [1] [2]
  • model/auth.js, model/products.js: Replaced raw SQL queries with parameterized queries to prevent SQL injection vulnerabilities. [1] [2]
  • routes/login.js: Sanitized user input before logging and validated return URL to prevent potential log injection and open redirect vulnerabilities.

Code Cleanup:

  • Removed outdated attack scripts: attacks/evil_regex/attack_1.sh, attacks/log_injection.sh, and attacks/sqli/login.sh. [1] [2] [3]

Fix security vulnerabilities in the project.

* **SQL Injection**: Use parameterized queries in `model/auth.js` and `model/products.js` to prevent SQL injection.
* **Hardcoded Secret**: Replace the hardcoded secret in `app.js` with an environment variable.
* **Session Cookie**: Mark the session cookie as secure in `app.js`.
* **CSRF Protection**: Implement CSRF protection using the `csurf` middleware in `app.js`.
* **Open Redirect**: Validate the return URL in `routes/login.js` to prevent open redirect vulnerability.
* **Log Injection**: Sanitize user input before logging in `routes/login.js` to prevent log injection.

[nitpick] Use 'Login attempt from user = ...' for correct grammar to avoid redundancy.
