Vulnerability discussion

The goal is to completely control the web user's experience in navigating any portion of the web document root directories. Ensuring all web content directories have at least the equivalent of an index.html file is a significant factor to accomplish this end.Enumeration techniques, such as URL parameter manipulation, rely upon being able to obtain information about the web server's directory structure by locating directories without default pages. In the scenario, the web server will display to the user a listing of the files in the directory being accessed. By having a default hosted application web page, the anonymous web user will not obtain directory browsing information or an error message that reveals the server type and version.As a web server, tc Server can be vulnerable to enumeration techniques if steps are not taken to mitigate the vulnerability. Ensuring that every document directory has an “index.jsp” (or equivalent) file is one common sense approach to mitigating the vulnerability.

Check content

At the command prompt, execute the following command: grep -E -A 4 ' node is not set to a default web page, this is a finding.

Fix text

Navigate to and open /usr/lib/vmware-casa/casa-webapp/conf/web.xml. Inspect the file and ensure that it contains the below section: index.html index.htm index.jsp

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.
