CVE-2022-40684Fortinet FortiOS — Authentication Bypass on the Admin Interface

Fortinet devices accept administrative requests arriving by an alternate path without checking who sent them, so an unauthenticated attacker changes the configuration outright.

YOUR NEXT MOVE

Upgrade past FortiOS 7.2.1 or 7.0.6 per Fortinet's advisory, and audit administrator accounts and configuration changes.
