Fix Recommendation

From the Tomcat server as a privileged user:

Edit the $CATALINA_BASE/conf/web.xml file.

Examine the <init-param> elements within the <Servletclass> element, if the "listings" <param-value>element is "true" change the "listings" <param-value> to read "false".

sudo systemctl restart tomcat
sudo systemctl daemon-reload

Check Contents

From the Tomcat server run the following OS command:

sudo cat $CATALINA_BASE/conf/web.xml |grep -i -A10 -B2 defaultservlet

The above command will include ten lines after and two lines before the occurrence of "defaultservlet". Some systems may require that the user increase the after number (A10) in order to determine the "listings" param-value.

If the "listings" param-value for the "DefaultServlet" servlet class does not = "false", this is a finding.
