Hi
Web server hosting the application disclosing the version number of its software.
The following response shows how the web server version was disclosed in the Sever HTTP header:
HTTP/1.1 200 OK
Server: Microsoft-IIS/7.5
x-frame-options:
Set-Cookie: ; path=/; HttpOnly
X-AspNet-Version: 4.0.3458
X-Powered-By: ASP.NET
Date: Wed, 18 June 2017 10:25:47 GMT
How Can I Prevent that?
