CVE-2022-30234Network attack vector

Unauthenticated code execution via hard-coded credentials

Published Jun 2, 2022 · Updated Sep 16, 2024

Hard-coded credentials in Schneider Electric Wiser Smart EER21000 and EER21001 before 4.5 allow remote attackers to execute arbitrary code. Schneider Electric has not disclosed where the embedded credentials reside or which network service accepts them. Network access requires neither prior authentication nor user interaction; successful use grants root-level control of the controller.
