🔍 How to Verify
Check if Vulnerable:
Test the Forgot Password functionality by attempting to inject basic XSS payloads (e.g., <script>alert('XSS')</script>) and observe if they execute.Check Version:
Check application documentation or interface for version information. Typically found in admin panels or about pages.Verify Fix Applied:
After implementing workarounds, retest with XSS payloads to confirm they are properly sanitized or blocked.📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to Forgot Password endpoints containing script tags or JavaScript code
- Multiple failed password reset attempts from single IPs
Network Indicators:
- HTTP requests with suspicious parameters containing <script>, javascript:, or other XSS indicators
SIEM Query:
source="web_logs" AND (uri_path="/forgot-password" OR uri_path="/reset-password") AND (request_body CONTAINS "<script>" OR request_body CONTAINS "javascript:")
