The DefaultServlet serves static resources as well as directory listings. It is declared globally in $CATALINA_BASE/conf/web.xml and by default is configured with the directory "listings" parameter set to disabled. If no welcome file is present and the "listings" setting is enabled, a directory listing is shown. Directory listings must be disabled. |

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. |
