CVE-2024-2013Network attack vector

Unauthenticated service access via API Gateway bypass

Published Jun 11, 2024 · Updated Aug 1, 2024

Authentication bypass in Hitachi Energy FOXMAN-UN and UNEM affected releases allows remote attackers to access protected server services. The vendor identifies the server API Gateway and maps an alternate authentication path or channel, but does not disclose the faulty route or operation. No credentials or user interaction are required; successful exploitation reaches services and the post-authentication attack surface.
