Eaton easyE4 uses an insufficiently strong password policy. An attacker who obtains a password hash, including through CVE-2026-41020, could perform an offline password-guessing attack and potentially recover user credentials.

Eaton easyE4 uses a static nonce during authentication, which could allow an unauthenticated attacker with access to captured authentication traffic to replay a valid authentication exchange and gain unauthorized access to the device.
