You Should Know:
1. Information Disclosure Vulnerabilities
- What it is: Unintended exposure of sensitive data (e.g., API keys, credentials, internal paths).
- How to Find It:
- Use `curl` to inspect HTTP headers:
curl -I https://target.com
– `gobuster` for directory brute-forcing:
gobuster dir -u https://target.com -w /path/to/wordlist.txt
– `ffuf` for fuzzing endpoints:
ffuf -u https://target.com/FUZZ -w /path/to/wordlist.txt
2. Cross-Site Scripting (XSS) Exploitation
- Types: Stored, Reflected, DOM-based.
- Testing Payloads:
<script>alert(1)</script> <img src=x onerror=alert(1)>
- Automated Scanning with
XSStrike:python3 xsstrike.py -u "https://target.com/search?q=test"
3. Business Logic Errors
- Example: Price manipulation, flawed authentication.
- Tools:
- Burp Suite (for intercepting/modifying requests).
– `sqlmap` (for testing logic flaws leading to SQLi):sqlmap -u "https://target.com/login" --data="user=admin&pass=test" --level=3
4. Reporting on HackerOne
- Steps:
1. Verify reproducibility.
2. Write a clear PoC (Proof of Concept).
3. Submit via HackerOne’s VDP portal.
What Undercode Say:
Bug bounty hunting requires persistence, automation, and deep knowledge of web vulnerabilities. Tools like nmap, Metasploit, and `OWASP ZAP` can enhance testing. Always follow responsible disclosure—avoiding unnecessary damage.
Expected Output:
- Vulnerability Reports (e.g., XSS, Info Disclosure).
- Triaged/Duplicate Status Updates (as seen in Toyota/MTN cases).
- Improved Recon Skills (using
Amass,Subfinder).
Prediction:
As VDPs grow, expect more automation in bug hunting (AI-driven scanners like DeepExploit). Companies will prioritize fast patching, making logic flaws the next big bounty target.
