Resource mapping is the process of tying a particular file type to a process in the web server that can serve that type of file to a requesting client and to identify which file types are not to be delivered to a client. By not specifying which files can and which files cannot be served to a user, the web server could deliver to a user web server configuration files, log files, password files, etc. As a derivative of the Apache Tomcat project, tc Server is a java-based web server. As a result, the main file extension used by tc Server is “*.jsp”. This check ensures that the “*.jsp” file type has been properly mapped to servlets.
At the command prompt, execute the following command: grep -E '<url-pattern>\*\.jsp</url-pattern>' -B 2 -A 2 /usr/lib/vmware-casa/casa-webapp/conf/web.xml If the “jsp” and “jspx” file extensions have not been mapped to the JSP servlet, this is a finding.
Navigate to and open /usr/lib/vmware-casa/casa-webapp/conf/web.xml.
Navigate to and locate the mapping for the JSP servlet. It is the <servlet-mapping> node that contains <servlet-name>jsp</servlet-name>.
Configure the <servlet-mapping> node to look like the code snippet below:
<!-- The mappings for the JSP servlet -->
<servlet-mapping>
<servlet-name>jsp</servlet-name>
<url-pattern>*.jsp</url-pattern>
<url-pattern>*.jspx</url-pattern>
</servlet-mapping>
