The vCenter VAMI service must have resource mappings set to disable the serving of certain file types.

Resource mapping is the process of tying a particular file type to a process in the web server that can serve that type of file to a requesting client and to identify which file types are not to be delivered to a client.

By not specifying which files can and which files cannot be served to a user, VAMI could deliver sensitive files.

At the command prompt, run the following command:

# grep "url.access-deny" /var/lib/vmware/cap-lighttpd/lighttpd.conf

Example result:

url.access-deny = ( "~", ".inc" )

If "url.access-deny" is not set to "( "~", ".inc" )", this is a finding.

Note: The command must be run from a bash shell and not from a shell generated by the "appliance shell". Use the "chsh" command to change the shell for the account to "/bin/bash". Refer to KB Article 2100508 for more details:

Navigate to and open:

/var/lib/vmware/cap-lighttpd/lighttpd.conf

Add or reconfigure the following value:

url.access-deny = ( "~", ".inc" )

Restart the service with the following command:

# systemctl restart cap-lighttpd
