X-aspnetmvc-version [hot] Guide

The X-AspNetMvc-Version header offers no operational value to end users and actively contributes to information leakage. Organizations deploying ASP.NET MVC should adopt header stripping as a standard hardening measure, aligning with principles of minimizing attack surface. The act of removal does not patch vulnerabilities but frustrates automated scanning and low-effort reconnaissance.

curl -I https://example.com | grep -i X-AspNetMvc Expected output: (none). x-aspnetmvc-version

Response.Headers.Remove("X-AspNetMvc-Version"); x-aspnetmvc-version
