VCLD-80-000102 The vCenter VAMI service must enable Content Security Policy.

Information

A Content Security Policy (CSP) requires careful tuning and precise definition of the policy. If enabled, CSP has significant impact on the way browsers render pages (e.g., inline JavaScript is disabled by default and must be explicitly allowed in the policy). CSP prevents a wide range of attacks, including cross-site scripting and other cross-site injections.

Solution

Navigate to and open:

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

If header "Content-Security-Policy" is not present, add the following line to the end of the file:

setenv.add-response-header += ("Content-Security-Policy" => "default-src 'self'; img-src 'self' data: https://vcsa.vmware.com; font-src 'self' data:; object-src 'none'; style-src 'self' 'unsafe-inline'")

If header "Content-Security-Policy" is present and not set to "default-src 'self'; img-src 'self' data: https://vcsa.vmware.com; font-src 'self' data:; object-src 'none'; style-src 'self' 'unsafe-inline'", update the value as shown below:

"Content-Security-Policy" => "default-src 'self'; img-src 'self' data: https://vcsa.vmware.com; font-src 'self' data:; object-src 'none'; style-src 'self' 'unsafe-inline'",

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
