Discussion

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.

Check Content

At the command prompt, run the following command:

# grep "url.access-deny" /opt/vmware/etc/lighttpd/lighttpd.conf

Expected result:

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

If the output does not match the expected result, 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:

Fix Text

Navigate to and open:

/opt/vmware/etc/lighttpd/lighttpd.conf

Add or reconfigure the following value:

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

Restart the service with the following command:

# vmon-cli --restart applmgmt
