Meta’s Bug Bounty program is a prime opportunity for security researchers to uncover vulnerabilities and earn rewards. Selecting the right research area is crucial for maximizing impact and success.
Key Research Areas to Target
1. Authentication & Authorization Flaws
- Focus on OAuth misconfigurations, session fixation, or JWT vulnerabilities.
- Test for insecure direct object references (IDOR) in API endpoints.
2. API Security
- Look for improper rate limiting, GraphQL injections, or data exposure.
- Use tools like Burp Suite or Postman to fuzz API endpoints.
3. Cross-Site Scripting (XSS) & CSRF
- Test for stored, reflected, and DOM-based XSS in Meta’s web apps.
- Check CSRF protections in sensitive actions (e.g., account changes).
4. Server-Side Request Forgery (SSRF)
- Probe internal service interactions via image uploads or webhooks.
5. Business Logic Vulnerabilities
- Explore flaws in payment systems, privacy controls, or account recovery.
You Should Know: Essential Commands & Tools
- Burp Suite:
java -jar burpsuite_pro.jar
- Nmap for Recon:
nmap -sV --script vuln target.meta.com
- SQLi Testing with SQLmap:
sqlmap -u "https://target.meta.com/search?q=1" --dbs
- Automated XSS Scanning with XSStrike:
python3 xsstrike.py -u "https://target.meta.com/profile"
- JWT Tampering with
jwt_tool:python3 jwt_tool.py <JWT_TOKEN> -T
Steps to Submit a Valid Report
1. Document the Bug: Record steps with screenshots/videos.
2. Reproduce Consistently: Ensure the flaw isn’t intermittent.
3. Write a Clear Report: Include:
- Vulnerability type.
- Impact.
- Proof of Concept (PoC).
- Submit via Meta’s Portal: Meta Bug Bounty.
What Undercode Say
Meta’s bounty program prioritizes real-world impact. Focus on high-severity bugs like RCE, data leaks, or authentication bypasses. Use Linux tools like `curl` for API testing:
curl -X POST https://api.meta.com/v1/endpoint -H "Authorization: Bearer TOKEN" --data "payload=test"
For Windows researchers, PowerShell aids in SSRF checks:
Invoke-WebRequest -Uri "http://internal.meta.com" -Method GET
Always stay updated with Meta’s program scope and rules.
Expected Output:
A well-documented bug report with a clear PoC, leading to a bounty reward.
