VCUI-70-000031 - vSphere UI must disable the shutdown port.

Information

An attacker has at least two reasons to stop a web server. The first is to cause a denial of service, and the second is to put in place changes the attacker made to the web server configuration. If the Tomcat shutdown port feature is enabled, a shutdown signal can be sent to vSphere UI through this port. To ensure availability, the shutdown port must be disabled.

Solution

Navigate to and open:

/usr/lib/vmware-vsphere-ui/server/conf/server.xml

Ensure the server port is disabled:

<Server port='${shutdown.port}'>

Restart the service with the following command:

# vmon-cli --restart vsphere-ui
