Reverse Proxy Detected
Description
A reverse proxy, load balancer, Content Delivery Network (CDN), or cloud hosting infrastructure has been detected in front of this web server. This was identified by analyzing variations in HTTP response headers and content when different request payloads were sent. While this is an informational finding, it indicates an additional network layer between clients and the origin server that may affect security testing and application behavior.
Remediation
No immediate action is required as this is an informational finding. However, consider the following best practices:
1. Ensure the reverse proxy or CDN is properly configured with security headers (X-Frame-Options, Content-Security-Policy, Strict-Transport-Security).
2. Verify that sensitive information is not being cached inappropriately by reviewing cache-control headers.
3. Implement proper access controls to ensure only the reverse proxy can communicate with the origin server (e.g., IP whitelisting, mutual TLS).
4. Monitor proxy logs for suspicious activity and potential attack patterns.
5. Keep the proxy software up to date with the latest security patches.
6. Document the proxy architecture for security testing purposes to ensure comprehensive vulnerability assessments.
