Senserva AI Opinion for CVE-2023-46805

The authentication bypass half of the Ivanti Connect Secure zero-day pair that opened 2024: it lets attackers slip past control checks in the web component, and chained with the CVE-2024-21887 command injection it gave unauthenticated code execution on VPN gateways worldwide. The campaign was severe enough that CISA ordered emergency disconnections of federal appliances. EPSS is 100 percent and ransomware use followed the initial espionage wave.

Do this: Confirm every Ivanti Connect Secure or Policy Secure appliance was rebuilt on fixed firmware after the January 2024 campaign, not just patched over a possible compromise.
