Fortinet’s warning about critical RCE vulnerabilities in FortiSandbox and FortiAuthenticator highlights the risk of security infrastructure itself becoming an attack path. FortiSandbox is designed to detect and analyze suspicious files, while FortiAuthenticator is tied to identity and access control. A remote code execution flaw in either system can therefore have consequences far beyond a single appliance, especially in enterprise environments where these products are deeply integrated into authentication, threat detection, and security workflows.

Security tools must be maintained with the same urgency as internet-facing business applications, because attackers do not care whether the vulnerable box has the word “security” printed on it. If anything, that just makes it a more attractive target, because irony apparently scales very well in cybersecurity.
