CVE-2022-30235Network attack vector

Unauthenticated access via unrestricted password guessing

Published Jun 2, 2022 · Updated Sep 16, 2024

Improper login-attempt restriction in Schneider Electric Wiser Smart before 4.5 allows remote attackers to gain unauthorized access. The EER21000 and EER21001 authentication interface does not restrict repeated password guesses; Schneider Electric has not disclosed a narrower code-level locus. No prior authentication or user interaction is required, and successful guessing exposes protected information without reported integrity or availability impact.
