• File: src/test/java/com/scalesec/vulnado/UserTests.java (added)

  • Unit tests for the User class, covering token generation, authentication, and database fetching.
  • Tests for valid and invalid tokens, and exception handling.

• File: src/test/java/com/scalesec/vulnado/VulnadoApplicationTests.java (modified)

  • Added tests for application initialization and database setup.

• Documentation Files (added):

  • Detailed documentation for Comment, CommentsController, CowController, Cowsay, LinkLister, LinksController, LoginController, Postgres, User, and VulnadoApplication.
  • Includes process flows, insights, dependencies, vulnerabilities, and recommendations.

Recommendation:

1. Improve Input Validation:

   • Ensure all user inputs are validated and sanitized to prevent injection attacks.
   • For example, in Comment.create, validate username and body before passing them to the database.

2. Enhance Password Security:

   • Replace MD5 hashing with a stronger algorithm like bcrypt or Argon2 for password storage.

3. Close Database Connections Properly:

   • Use try-with-resources or ensure connections are closed in a finally block to prevent resource leaks.

4. Restrict CORS Origins:

   • Replace @CrossOrigin(origins = "*") with a list of trusted domains to prevent cross-origin attacks.

5. Implement Rate Limiting:

   • Add rate limiting to endpoints like login to mitigate brute-force attacks.

6. Secure Logging:

   • Avoid logging sensitive information like database credentials or user tokens.

7. Handle Exceptions Effectively:

   • Provide detailed error messages for debugging while ensuring sensitive information is not exposed to users.

8. Review Command Execution:

   • In Cowsay.run, ensure all inputs are sanitized to prevent command injection.

Explanation of vulnerabilities:

1. SQL Injection in User.fetch:

   • Vulnerable code:

     String query = "select * from users where username = '" + un + "' limit 1";

   • Suggested fix:

     String query = "SELECT * FROM users WHERE username = ? LIMIT 1";
     PreparedStatement stmt = connection.prepareStatement(query);
     stmt.setString(1, un);

2. Insecure Password Hashing:

   • Vulnerable code:

     public static String md5(String input) {
         MessageDigest md = MessageDigest.getInstance("MD5");
         return new BigInteger(1, md.digest(input.getBytes())).toString(16);
     }

   • Suggested fix: Use bcrypt or Argon2 for hashing passwords.

3. Command Injection in Cowsay.run:

   • Vulnerable code:

     ProcessBuilder pb = new ProcessBuilder("/usr/games/cowsay", input);

   • Suggested fix: Validate and sanitize input to remove all special characters.

4. SSRF in LinkLister.getLinks:

   • Vulnerable code:

     Document doc = Jsoup.connect(url).get();

   • Suggested fix: Validate the URL to ensure it points to a trusted domain.

5. Unrestricted CORS:

   • Vulnerable code:

     @CrossOrigin(origins = "*")

   • Suggested fix: Restrict origins to trusted domains.

6. Hardcoded Secret:

   • Vulnerable code:

     @Value("${app.secret}")
     private String secret;

   • Suggested fix: Store secrets securely using a vault or environment variables with restricted access.

By addressing these vulnerabilities and implementing the recommendations, the application can be made more secure and robust.
