Vulnerability discussion

A web server can be installed with functionality that, 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.

Check content

In a command line, run "httpd -M | sort" 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

Fix text

Determine where the "dav" modules are located by running the following command: grep -rl "dav_module" <'INSTALL PATH'> Edit the file and comment out the following modules: dav_module dav_fs_module dav_lock_module Restart Apache: apachectl restart

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.
