Discussion

Tomcat by default listens on TCP port 8005 to accept shutdown requests. By connecting to this port and sending the SHUTDOWN command, all applications within Tomcat are halted. The shutdown port is not exposed to the network as it is bound to the loopback interface. Setting the port to "-1" in $CATALINA_BASE/conf/server.xml instructs Tomcat to not listen for the shutdown command.

Check Content

At the command prompt, run the following commands:

# xmllint --xpath "//Server/@port" /usr/lib/vmware-vsphere-ui/server/conf/server.xml
# grep shutdown.port /etc/vmware/vmware-vmon/svcCfgfiles/vsphere-ui.json

Example results:

port="${shutdown.port}"
"-Dshutdown.port=-1",

If "port" does not equal "${shutdown.port}", this is a finding.

If "shutdown.port" does not equal "-1", this is a finding.

Fix Text

Navigate to and open:

/usr/lib/vmware-vsphere-ui/server/conf/catalina.properties

Add or modify the setting "shutdown.port=-1" in the "catalina.properties" file.

Navigate to and open:

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

Configure the <Server> node with the value:

port="${shutdown.port}"

Restart the service with the following command:

# vmon-cli --restart vsphere-ui
