Web security can be overwhelming, especially with concepts like OWASP, Burp Suite, payloads, CORS, CSRF, and XSS. The key is to focus on one vulnerability at a time. Here’s a structured approach:
- Pick One Bug Class (e.g., IDOR – Insecure Direct Object Reference).
- Find 3 Real Writeups on platforms like HackTheBox, PortSwigger, or Medium.
- Recreate the Exploits step-by-step in a lab environment.
- Hunt on HackerOne focusing only on that vulnerability.
You Should Know:
Practical Steps for IDOR Testing
- Identify Object References in URLs or API requests (e.g.,
/user?id=123).
2. Modify Parameters (e.g., change `id=123` to `id=124`).
- Check for Unauthorized Access using Burp Suite or browser dev tools.
Burp Suite Commands:
Intercept a request burpsuite & Send a request to Repeater for manipulation Ctrl + R
Linux Tools for Web Security:
Use curl to test IDOR curl -H "Cookie: session=XYZ" http://example.com/user?id=124 Use ffuf for parameter fuzzing ffuf -w wordlist.txt -u "http://example.com/user?id=FUZZ"
Windows Command for Testing:
Check HTTP responses Invoke-WebRequest -Uri "http://example.com/user?id=124"
What Undercode Say:
Focusing on one vulnerability at a time builds expertise faster than scattered learning. Use labs like TryHackMe or HackTheBox for hands-on practice.
Prediction:
As web apps grow more complex, IDOR and similar logic flaws will remain a top attack vector. Automated scanners will improve, but manual testing will still dominate.
Expected Output:
- A structured learning path for web security.
- Hands-on commands for testing IDOR.
- Emphasis on focused, practical learning.
