ESX Agent Manager must disable the shutdown port.

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 the ESX Agent Manager through this port. To ensure availability, the shutdown port must be disabled.

At the command prompt, run the following command:

# grep 'base.shutdown.port' /etc/vmware-eam/catalina.properties

Expected result:

base.shutdown.port=-1

If the output of the command does not match the expected result, this is a finding.

Navigate to and open:

/etc/vmware-eam/catalina.properties

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

Restart the service with the following command:

# vmon-cli --restart eam
