Cockpit CMS 2.12.0 before 2.14.1 disables TLS certificate verification in the cron.php web worker restart request, allowing network attackers to capture the worker token. Man-in-the-middle attackers on the outbound path to site_url can present any certificate to steal the worker/web/token value and start the web worker.
Weakness
The product does not validate, or incorrectly validates, a certificate.
