CVE-2022-46680Network attack vector

Credential disclosure via plaintext ION/TCP messages

Published May 22, 2023 · Updated Jan 21, 2025

Cleartext credential transmission in Schneider Electric PowerLogic ION meters allows man-in-the-middle attackers to capture account credentials. Enabled ION/TCP sessions send the user ID and password in plaintext with every message over TCP port 7700. An attacker must intercept network traffic; captured credentials grant access to engineering, SSH, or HTTP interfaces and permit configuration changes.
