Q: You are given only a login page. What are some testing approaches?
A: When only a login page is available, consider the following testing approaches:
- Vulnerability Scanning: Test for client-side and server-side vulnerabilities like XSS and SQL injection.
- Username Enumeration: Attempt to enumerate valid usernames and test common passwords.
- HTTP Header Analysis: Examine HTTP headers for information disclosure or misconfigurations.
- Brute Force: Attempt a brute-force attack to guess valid credentials.
- Payload Injection: Try injecting payloads into login forms to bypass authentication.
- API Testing: Check for available APIs and test them for vulnerabilities.
- SSL/TLS Certificate Check: Verify the validity of the SSL/TLS certificate.
- Directory/Path Traversal: Attempt to access restricted folders or files.
- Credential Storage: Check for credentials stored in plaintext.
- State Manipulation: Test the impact of clearing or modifying cookies and headers.
