VCLU-70-000023 - Lookup Service must be configured to hide the server version.

Information

Web servers will often display error messages to client users, including 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, Lookup Service must be configured to hide the server version at all times.

Solution

Navigate to and open:

/usr/lib/vmware-lookupsvc/conf/server.xml

Navigate to each of the <Connector> nodes.

Configure each <Connector> node with 'server='Anonymous''.

Restart the service with the following command:

# vmon-cli --restart lookupsvc
