Administrative access via unauthenticated SSO endpoint
Published Oct 8, 2026 · Updated Oct 8, 2026
Authentication bypass in Brocade Communications Systems Fabric OS before 9.2.2d on MXG610 allows remote attackers administrative access. The web management SSO workflow exposes an endpoint that omits authentication before granting access to administrative controls; the exact endpoint and request sequence are undisclosed. Exploitation requires network adjacency to an MXG610 management interface, and the reported impact is administrative control of that interface.
