Senserva AI Opinion for CVE-2022-23176

WatchGuard Firebox and XTM appliances let a remote attacker with only unprivileged credentials obtain a privileged management session through exposed management access, a High Severity flaw (CVSS 8.8) with confirmed exploitation per CISA KEV (2022-04-11). Perimeter firewalls are a prized target because owning one gives an attacker a stable position outside your endpoint tooling. The 13% EPSS score understates the risk to any appliance whose management interface faces the internet.

Do this: Patch Firebox and XTM appliances and restrict their management interfaces to internal management networks only.
