Web servers will often display error messages to client users with enough information to aid in the debugging of the error. The information given back in error messages may display the web server type, version, patches installed, plug-ins and modules installed, type of code being used by the hosted application, and any backends being used for data storage. This information could be used by an attacker to blueprint what type of attacks might be successful. Therefore, vSphere UI must be configured to not show server version information in error pages.


Navigate to and open /usr/lib/vmware-vsphere-ui/server/conf/server.xml.

Locate the following Host block:

<Host name='localhost'' ...>

Inside this block, add the following on a new line:

<Valve className='org.apache.catalina.valves.ErrorReportValve' showServerInfo='false'/>
