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. As Tomcat is a Java-based web server, the main file extension used is *.jsp. This check ensures the *.jsp and *.jspx file types have been properly mapped to servlets.

At the command prompt, run the following command:

# xmllint --format /usr/lib/vmware-sso/vmware-sts/conf/web.xml | sed '2 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 output of the command does not match the expected result, this is a finding.
