Vulnerability discussion

Apache web server documentation, sample code, example applications, and tutorials may be an exploitable threat to an Apache web server because this type of code has not been evaluated and approved. A production Apache web server must only contain components that are operationally necessary (e.g., compiled code, scripts, web content, etc.).Any documentation, sample code, example applications, and tutorials must be removed from a production Apache web server. To ensure that the documentation and code are not installed or are uninstalled completely, the Apache web server must offer an option as part of the installation process to exclude these packages or to uninstall the packages if necessary.

Check content

If the site requires the use of a particular piece of software, verify that the Information System Security Officer (ISSO) maintains documentation identifying this software as necessary for operations. The software must be operated at the vendor’s current patch level and must be a supported vendor release. If programs or utilities that meet the above criteria are installed on the web server and appropriate documentation and signatures are in evidence, this is not a finding. Determine whether the web server is configured with unnecessary software. Determine whether processes other than those that support the web server are loaded and/or run on the web server. Examples of software that should not be on the web server are all web development tools, office suites (unless the web server is a private web development server), compilers, and other utilities that are not part of the web server suite or the basic operating system. Check the directory structure of the server and verify that additional, unintended, or unneeded applications are not loaded on the system. If, after review of the application on the system, there is no justification for the identified software, this is a finding.

Fix text

Remove any unnecessary applications per ISSO documentation.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
