⚡ Key issues to review **Possible Bug:** The logic in `ValidateRequestCerts` function in `internal/crypto/helpers.go` has been changed to loop through all peer certificates and match against a list of allowed certificates. This change might introduce issues if the peer presents multiple certificates and the first one is not the one expected to match. It would be safer to ensure that the correct certificate is being validated against the allowed list. **Data Consistency:** The addition of the `IsCA` field in various structures (`CertificateBasics`, `CertificateMeta`) needs to be thoroughly tested to ensure that it is correctly populated in all relevant API responses and internal logic where these structures are used. |

Add error handling after URL parsing to ensure stability___ **Consider checking for errors after parsing the URL. This ensures that any issueswith URL parsing are caught early, preventing potential runtime panics or misbehaviors in subsequent requests.** [gateway/cert_test.go [1903-1904]](https://github.com/TykTechnologies/tyk/pull/6406/files#diff-481696cb18de8c3880e0ca21318fe00fd4eb89bc48994e43b7c34729ef4a7ee2R1903-R1904) ```diff u, err := url.Parse(ts.URL) +if err != nil { + t.Fatalf("Failed to parse URL: %v", err) +} ``` Suggestion importance[1-10]: 9Why: Adding error handling after URL parsing is crucial for preventing potential runtime panics or misbehaviors, which enhances the robustness of the code. | 9 | |

Use a unique serial number for certificates to enhance security___ **Instead of using a hardcoded value for the serial number, consider generating arandom or unique serial number for each certificate to enhance security and comply with best practices.** [gateway/cert_test.go [1924]](https://github.com/TykTechnologies/tyk/pull/6406/files#diff-481696cb18de8c3880e0ca21318fe00fd4eb89bc48994e43b7c34729ef4a7ee2R1924-R1924) ```diff -SerialNumber: big.NewInt(1), +SerialNumber: big.NewInt(rand.Int63()), // Ensure unique serial number ``` Suggestion importance[1-10]: 8Why: Using a unique serial number for certificates is a best practice that enhances security and ensures compliance with standards. | 8 |
Add assertions for response content to verify API behavior___ **To improve the robustness of the test, consider adding assertions to check thecontents of the response body in addition to the status code, ensuring that the API behaves as expected.** [gateway/cert_test.go [1888-1893]](https://github.com/TykTechnologies/tyk/pull/6406/files#diff-481696cb18de8c3880e0ca21318fe00fd4eb89bc48994e43b7c34729ef4a7ee2R1888-R1893) ```diff -_, _ = ts.Run(t, test.TestCase{ +response, _ := ts.Run(t, test.TestCase{ Domain: "localhost", Client: validCertClient, Path: "/static-mtls", Code: http.StatusOK, }) +assert.Contains(t, response.Body, "expected content") ``` Suggestion importance[1-10]: 7Why: Adding assertions for the response content improves the robustness of the test by ensuring that the API behaves as expected, not just returning the correct status code. | 7 | |
Improve the error message clarity when no valid certificate is found___ **Refactor the error message to include the type of error for clarity when no validcertificate is found.** [internal/crypto/helpers.go [126]](https://github.com/TykTechnologies/tyk/pull/6406/files#diff-3d1fc755c46eaa99e9f1edf358b9e00842342ae6333902959d7a68b46d156829R126-R126) ```diff -return errors.New("Certificate with SHA256 " + HexSHA256(r.TLS.PeerCertificates[0].Raw) + " not allowed") +return fmt.Errorf("Certificate validation failed: Certificate with SHA256 %s not allowed", HexSHA256(r.TLS.PeerCertificates[0].Raw)) ``` Suggestion importance[1-10]: 7Why: The suggestion improves the clarity of the error message, making it more informative. While this is a good enhancement, it is not as critical as preventing runtime panics. | 7 | |
