Senserva AI Opinion for CVE-2023-44221
SonicWall SMA100 remote access appliances allow an authenticated admin to inject OS commands through the SSL-VPN management interface, and in observed 2025 attacks this was the persistence step after credentials were stolen through other flaws. The 75 percent EPSS is remarkable for a bug that requires admin privilege, telling you how often attackers already hold SMA100 credentials. It entered the KEV catalog in May 2025.
Do this: Update SMA100 firmware and rotate all administrator credentials on the appliance, since exploitation presumes the attacker already logged in.
