Fix Recommendation

Navigate to and open:

/opt/vmware/etc/lighttpd/applmgmt-lighttpd.conf

If header "X-Frame-Options" is not present, add the following line to the end of the file:

setenv.add-response-header += ("X-Frame-Options" => "Deny")

If header "X-Frame-Options" is present and not set to "Deny", update the value as shown below:

"X-Frame-Options" => "Deny",

Note: The last line in the parameter does not need a trailing comma if part of a multi-line configuration.

Restart the service with the following command:

# systemctl restart cap-lighttpd

Check Contents

At the command prompt, run the following command:

# /opt/vmware/cap_lighttpd/sbin/lighttpd -p -f /var/lib/vmware/cap-lighttpd/lighttpd.conf 2>/dev/null|awk '/setenv\.add-response-header/,/\)/'|sed -e 's/^[ ]*//'|grep "X-Frame-Options"

Example result:

"X-Frame-Options" => "Deny",

If the response header "X-Frame-Options" is missing or not configured to "Deny", 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:
