Server header exposes version information
Description
The target website returns the Server header and version information of this website. By
exposing these values, attackers may attempt to identify if the target software is vulnerable to known
vulnerabilities, or catalog known sites running particular versions to exploit in the future when a
vulnerability is identified in the particular version.
Remediation
We recommend that the version information be removed from the Server header.
Apache:
For Apache based web sites, set the ServerTokens to Prod in the httpd.conf configuration file.
NGINX:
For NGINX based websites, set the server_tokens configuration value to off in the nginx.conf file.
IIS:
For IIS based websites version 10 and above you can use the removeServerHeader element to the requestFiltering
section of the Web.config file.
For all other server types, please consult your product's documentation on how to redact the version information from
the Server header.
