Several server side technologies send the X-Powered-By header. This gives clients quite a overview of what the server might be running, which allows malicious users to quite easily search for security vulnerabilities affecting the versions specified.

It is recommended to disable this header to prevent any leaking of potential information that could aid an attacker.

How do I fix this ?

For PHP, in your PHP.ini file:

expose_php = off

For IIS, by including these lines to the <system.webServer> element:

<httpProtocol>
    <customHeaders>
        <remove name="X-Powered-By" />
    </customHeaders>
</httpProtocol>

For ExpressJS:

app.disable('x-powered-by');
