Bug bounty programs like Microsoft’s offer opportunities for ethical hackers to discover vulnerabilities. In this case, HTML Injection and CSRF (Cross-Site Request Forgery) were identified as potential attack vectors.
You Should Know:
1. HTML Injection
HTML Injection occurs when an attacker injects malicious HTML/JS code into a vulnerable input field, leading to unauthorized actions.
Example Payload:
<script>alert("XSS")</script>
<img src="x" onerror="alert('HTML Injection')">
Testing Steps:
1. Identify input fields (forms, search bars, etc.).
2. Inject HTML/JS payloads.
- Check if the payload executes in the browser.
2. CSRF (Cross-Site Request Forgery)
CSRF tricks a user into executing unwanted actions on a web app where they’re authenticated.
Example CSRF Attack:
<form action="https://victim-site.com/change-email" method="POST"> <input type="hidden" name="email" value="[email protected]"> </form> <script>document.forms[bash].submit();</script>
Prevention:
- Use CSRF tokens in forms.
- Implement SameSite cookies.
- Require re-authentication for sensitive actions.
3. Bug Bounty Recon & Exploitation
Tools & Commands:
- Burp Suite (Intercept & modify requests)
- OWASP ZAP (Automated scanning)
- curl (Manual request testing)
curl -X POST "https://target.com/update" -d "user=admin&action=delete"
Linux Command for Log Analysis:
grep "CSRF" /var/log/apache2/access.log
Windows Command for Network Monitoring:
Get-WinEvent -LogName Security | Where-Object {$_.Id -eq 4688}
What Undercode Say
Microsoft’s bug bounty program highlights the importance of securing web apps against HTML Injection and CSRF. Ethical hackers must:
– Test input validation rigorously.
– Verify token-based protections.
– Report vulnerabilities responsibly.
Expected Output:
- Successful HTML injection leading to XSS.
- CSRF exploit changing user settings without consent.
- Bounty reward upon valid submission.
Prediction
As web apps grow more complex, HTML Injection and CSRF attacks will evolve, requiring stricter security measures like Content Security Policy (CSP) and multi-factor authentication (MFA). Bug bounty programs will continue to incentivize ethical hacking.
