The Apache web server must have Web Distributed Authoring (WebDAV) disabled.

A web server can be installed with functionality that, just by its nature, is not secure. WebDAV is an extension to the HTTP protocol that, when developed, was meant to allow users to create, change, and move documents on a server, typically a web server or web share. Allowing this functionality, development, and deployment is much easier for web authors.

WebDAV is not widely used and has serious security concerns because it may allow clients to modify unauthorized files on the web server.

In a command line, navigate to "<'INSTALLED PATH'>\bin". Run "httpd -M" to view a list of installed modules.

If any of the following modules are present, this is a finding:

dav_module dav_fs_module dav_lock_module

Edit the <'INSTALL PATH'>\conf\httpd.conf file and remove the following modules:

dav_module dav_fs_module dav_lock_module

Restart the Apache service.
