Message-queue data disclosure via hard-coded credential

Published Jan 5, 2023 · Updated Apr 10, 2025

Hard-coded credentials in affected Hitachi Energy FOXMAN-UN and UNEM releases allow local users to read internal message-queue data. The products embed a reusable credential for the internal message queue, allowing its holder to authenticate and access queued data; Hitachi Energy has not disclosed the credential's storage location or extraction path. Local access is required, and the documented impact is limited to confidentiality of data held in the internal queue.
