Description
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 identify which file types are not to be delivered to a client. By not specifying which files can and cannot be served to a user, the web server could deliver to a user web server configuration files, log files, password files, etc. Because Tomcat is a Java-based web server, the main file extension used is .jsp. This check ensures the .jsp and *.jspx file types has been properly mapped to servlets.

ℹ️ Check
At the command prompt, run the following command: # xmllint --format /usr/lib/vmware-lookupsvc/conf/web.xml \| sed 's/xmlns="."//g' \| xmllint --xpath '/web-app/servlet-mapping/servlet-name[text()="jsp"]/parent::servlet-mapping' - Expected result: <servlet-mapping> <servlet-name>jsp</servlet-name> <url-pattern>.jsp</url-pattern> <url-pattern>*.jspx</url-pattern> </servlet-mapping> If the .jsp and .jspx file url-patterns are not configured as in the expected result, this is a finding.

✔️ Fix
Navigate to and open: /usr/lib/vmware-lookupsvc/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> Restart the service with the following command: # vmon-cli --restart lookupsvc
