OSWE Authentication Bypass Techniques Quiz

1. What is a race condition in authentication context?

Simultaneous requests causing logic flaws in validation

Slow server response times

Concurrent user sessions

Sequential request processing

2. What is the risk of storing authentication tokens in local storage?

XSS attacks can steal tokens

Tokens persist across browser sessions

No HttpOnly flag protection

All of the above

3. How does parameter pollution enable authentication bypass?

Overwriting security checks with multiple parameters

Confusing parsing logic across layers

All of the above

4. Which bypass technique exploits null byte injection?

Null byte truncation in file paths

Buffer overflow attacks

XSS payload injection

CSRF token bypass

5. What is the impact of Broken Object Level Authorization (BOLA)?

Users can access other users' data by modifying object IDs

Database schema becomes visible

Server crashes from invalid requests

Network bandwidth is exhausted

6. How can attackers bypass API authentication?

API key enumeration and brute force

Exploiting missing rate limiting

Token prediction or reuse

All of the above

7. What is a default credential vulnerability?

Using manufacturer default usernames and passwords

Weak password policies

Expired authentication certificates

Hardcoded API keys in code

8. Which header manipulation can bypass authentication filters?

X-Forwarded-For spoofing

10. How can multi-factor authentication be bypassed?

Exploiting MFA bypass endpoints

SIM swapping for SMS codes

Brute-forcing OTP codes

All of the above

11. What is the primary goal of SQL injection attacks in authentication bypass?

All of the above

14. How can attackers exploit weak session management?

Session fixation attacks

Session hijacking via XSS

Predictable session IDs

All of the above

15. What is a common weakness in password reset functionality?

Cross-Site Request Forgery

17. What is a common vulnerability in OAuth 2.0 implementations?

Redirect URI validation bypass

State parameter tampering

Authorization code interception

All of the above

18. How can an attacker bypass authentication using JWT manipulation?

By modifying the payload and re-signing without key verification

By increasing the token expiration time

By removing the signature entirely and changing algorithm to 'none'

All of the above

19. What does JWT stand for in the context of web authentication?

Java Web Token

JSON Web Token

JavaScript Web Tunnel

Joint Web Transport

20. Which authentication mechanism is most vulnerable to timing attacks?
