CVE-2023-4606Network attack vector

Cross-account password reset via missing authorization

Published Oct 24, 2023 · Updated Sep 11, 2024

Missing authorization in Lenovo XClarity Controller lets remote authenticated users reset another account's password on ThinkSystem v2/v3 servers. The user-management API accepts a password-change command from a ReadOnly account without enforcing authorization for the targeted account. ReadOnly XCC access is sufficient to alter credentials for a different account, while Lenovo has not disclosed the affected API endpoint or request fields.
