Description
The default servlet (or DefaultServlet) is a special servlet provided with Tomcat that is called when no other suitable page is found in a particular folder. The DefaultServlet serves static resources as well as directory listings. The DefaultServlet is configured by default with the "readonly" parameter set to "true" where HTTP commands such as PUT and DELETE are rejected. Changing this to "false" allows clients to delete or modify static resources on the server and to upload new resources. DefaultServlet "readonly" must be set to "true", either literally or by absence (default).

Who does this work

10 NICE work roles and 9 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-256810r889429_chk)

At the command prompt, run the following command: # xmllint --format /usr/lib/vmware-vsphere-ui/server/conf/web.xml | sed 's/xmlns=".*"//g' | xmllint --xpath '/web-app/servlet/servlet-name[text()="default"]/../init-param/param-name[text()="readonly"]/../param-value[text()="false"]' - Expected result: XPath set is empty If the output of the command does not match the expected result, this is a finding.

Fix Text (F-60428r889428_fix)

Navigate to and open: /usr/lib/vmware-vsphere-ui/server/conf/web.xml Navigate to the /<web-apps>/<servlet>/<servlet-name>default</servlet-name>/ node and remove the following node: <init-param> <param-name>readonly</param-name> <param-value>false</param-value> </init-param> Restart the service with the following command: # vmon-cli --restart vsphere-ui
