Publishing to a Web Distributed and Authoring (DAV) server must be prevented.

Part of DTOO217 - Prevent publishing to DAV Servers

SV-33514r1_rule Publishing to a Web Distributed and Authoring (DAV) server must be prevented.

Vulnerability discussion

Outlook users can share their calendars with others by publishing them to a server that supports the World Wide Web Distributed Authoring and Versioning (WebDAV) protocol. Unlike the Microsoft Office Online Calendar Sharing Service, which allows users to manage other people's access to their calendars, DAV access restrictions can only be accomplished through server and folder permissions, and might require the assistance of the server administrator to set up and maintain. If these permissions are not managed properly, unauthorized people could access sensitive information.

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.
