Description
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. WebDAV is not widely used and has serious security concerns because it may allow clients to modify unauthorized files on the web server and must therefore be disabled. Tomcat uses the "org.apache.catalina.servlets.WebdavServlet" servlet to provide WebDAV services. Because the WebDAV service has been found to have an excessive number of vulnerabilities, this servlet must not be installed. ESX Agent Manager does not configure WebDAV by default.
