Summary

The Apache HTTP Server Project is a collaborative software development effort aimed at creating a robust, commercial-grade, featureful, and freely-available source code implementation of an HTTP (Web) server. The project is jointly managed by a group of volunteers located around the world, using the Internet and the Web to communicate, plan, and develop the server and its related documentation. This project is part of the Apache Software Foundation. In addition, hundreds of users have contributed ideas, code, and documentation to the project. This file is intended to briefly describe the history of the Apache HTTP Server and recognize the many contributors.

Apache Server Information Leakage

Server Token

Description

By Default Apache ServerToken directive reveals the below information.

Server: Apache/2.2.14 (Unix) mod_ssl/2.2.14 OpenSSL/0.9.8e-fips-rhel5

This allows attackers to identify web servers details greatly and increases the efficiency of any attack,as security vulnerabilities are dependent upon specific software versions.

How to test

In order to test for ServerToken configuration, one should check the Apache configuration file.

Misconfiguration

ServerTokens Full

Remediation

Configure the ServerTokens directive in the Apache configuration to value of Prod or ProductOnly

or
ServerTokens ProductOnly
