VCLD-70-000027 - VAMI must be configured to hide the server type and version in client responses - DoS attacks.

Information

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

Solution

Navigate to and open:

/etc/applmgmt/appliance/lighttpd.conf

Add or reconfigure the following value:

server.tag = 'vami'

Restart the service with the following command:

# vmon-cli --restart applmgmt
