C-APIPen Dumps (V8.02) for Your Certified API Pentester (C-APIPen) Exam Preparation: Come to Read the C-APIPen Free Dumps (Part 1, Q1-Q40) First

1. Locate potential sensitive operations in a Swagger (OpenAPI) definition.

2. Use Swagger UI to execute a GET request and analyze the response for excessive data exposure.

3. Identify broken access control by testing role-protected endpoints via Swagger.

4. Modify and test query parameters to check for SQL Injection via Swagger.

5. Discover undocumented endpoints using the Swagger file structure.

6. Enumerate all required parameters for an endpoint using Swagger UI.

7. Test for improper HTTP method exposure.

8. Check for insecure default values in Swagger parameter schemas.

9. Use Swagger schema to fuzz the API with invalid types.

10. Extract authentication mechanism from Swagger Security Definitions.

11. You have received a Swagger (OpenAPI) JSON file containing the API definition of a target system. Describe how you would import this file into Postman to generate a full set of request templates for manual and automated security testing.

12. Explain how you would verify that the imported API collection in Postman correctly preserves the authentication schemes and request parameters defined in the OpenAPI spec.

13. You want to quickly test multiple endpoints from a large imported Postman collection. Explain how to use Postman’s “Collection Runner” to automate these requests.

14. You’ve imported an API collection and need to test how it behaves with different user roles (admin vs. regular user). Explain how to configure and switch environments in Postman for this purpose.

15. You need to add a global header (e.g., X-API-Key) to every request in an imported collection.

How can you do this efficiently without editing each request manually?

16. Describe the process of exporting a modified Postman collection for sharing with your pentest team, ensuring they receive all endpoint data and configuration.

17. You suspect an endpoint is vulnerable to IDOR (Insecure Direct Object Reference). Using Postman collections, explain how you would test this vulnerability efficiently.

18. How would you organize a large imported Postman collection to focus on testing only POST and DELETE methods which are more likely to be vulnerable?

19. Explain how to add test scripts in Postman to automatically detect abnormal response codes (like 500, 403) for any request in the collection.

20. During your API pentest, you want to simulate a replay attack using a previously successful POST request in Postman.

How can you modify the request and observe the server's behavior?

21. You want to test an API for Broken Object Level Authorization (BOLA). The API provides access to user resources via /api/user/{userId}. Explain how you would identify and exploit a BOLA vulnerability.

22. The API exposes an endpoint /api/deleteAccount that accepts a userId in the body. Demonstrate how to check for Broken Function Level Authorization (BFLA).

23. How would you test for Excessive Data Exposure through a /api/profile endpoint returning JSON objects?

24. An API allows client-controlled filtering via /api/products?sort=price. Explain how to test for Mass Assignment vulnerabilities in such APIs.

25. You suspect an API is vulnerable to Security Misconfiguration. Describe a process to verify this through HTTP headers.

26. How would you identify a lack of rate limiting on a login endpoint /api/login?

27. An API endpoint /api/comments accepts input and reflects it in the response. Explain how to test for Injection (e.g., SQL, NoSQL).

28. You’re targeting an API using token-based authentication.

How would you test for Improper Assets Management?

29. Describe how to test for Insufficient Logging and Monitoring in an API handling authentication or sensitive actions.

30. Explain how to exploit a Vulnerable API lacking proper CORS policies that allows unauthorized cross-origin requests.

31. You are testing an API endpoint that accepts XML input. Describe how to craft a basic payload to detect a potential XML External Entity (XXE) vulnerability.

32. Explain how to test for file disclosure using XXE to read system files like /etc/passwd.

33. You want to identify blind XXE where no file content is reflected in the response.

How do you exfiltrate data using an out-of-band (OOB) XXE?

34. You encounter an API that uses SOAP.

How would you inject an XXE payload into a SOAP message?

35. How can you check if the server uses DTD (Document Type Definition) processing to confirm potential XXE vectors?

36. Demonstrate how to test for SSRF via XXE using a local endpoint like http://localhost:8080/.

37. You want to extract server environment variables using XXE. Explain the steps and payload.

38. You suspect the server is running on Windows.

How would you modify your XXE payload to confirm OS type?

39. You want to combine XXE with a Denial of Service (DoS) attack.

How would you perform a "Billion Laughs" attack?

40. You need to verify if XML parsing is safe.

What headers or behaviors in the HTTP response might indicate secure XML parsing?
