A flaw was found in Foreman. The Red Hat Satellite /unattended/provision API endpoint is vulnerable to an authentication bypass due to a semantic logic flaw in host_verifier.rb. The application verifies the database state of a provisioning token rather than its actual presence in the incoming HTTP request. Because a host actively undergoing provisioning has an unexpired token in the database, the server's valid_host_token? method evaluates to true, granting access to the kickstart template even if the requester provides no token at all in the URL.
