Server Leaks Information via 'X-Powered-By' HTTP Response Header Field(s)

Summary

The web/application server is leaking information via one or more “X-Powered-By” HTTP response headers. Access to such information may facilitate attackers identifying other frameworks/components your web application is reliant upon and the vulnerabilities such components may be subject to.

Risk

Low

Solution

Ensure that your web server, application server, load balancer, etc. is configured to suppress 'X-Powered-By' headers.
