No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

The affected Watchfire Controller Software contains self-signed hard-coded RSA private keys and corresponding X.509 certificates used for authenticating and encrypting HTTPS/TLS connections to the controller's built-in web management interface. These keys are embedded in plaintext within the application patch binaries in the firmware directly from Watchfire's Remote Support filestore.
