How to Enable Validation of the Host Header of a Request

To enable validation of host header of a request based on a regular expression,

Access the UCMDB server JMX console: Launch a Web browser and enter the following address: https://<UCMDB machine name or IP address>:8443/jmx-console. You may have to log in with a user name and password (default user name: sysadmin).
Locate UCMDB:service=Settings Services and click the link to jump to the Operations table.
Locate the setGlobalSettingValue operation.
To enable validation of host header of a request, provide values for the following parameters for the setGlobalSettingValue method:
- name: security.filter.header.allowed.host
- value: <enter a JAVA regex that matches a valid host>
  
  For example,
  - mymachine, will only accepts a host header that contains the value mymachine.
  - mymachine.*|localhost, will accept mymachine.mydomain.com, mymachine.subd1.domain1.com or any domain starting with mymachine or localhost as host.
  The default value of the security.filter.header.allowed.host setting is .*. It affects URLs containing /ucmdb-ui/ only. For example, https://localhost:8443/ucmdb-ui/applet/applet.jsp.
Click Invoke. The setting takes effect immediately.
Restart the whole UCMDB cluster to ensure that the setting is picked up by all readers.
