Adjacent authentication bypass via unauthenticated SSH server
Published Mar 10, 2025 · Updated Mar 12, 2025
Authentication bypass in GE Vernova EnerVista UR Setup 7.0 through 8.60 allows man-in-the-middle attackers to impersonate an SSH relay server. The client establishes its SSH channel without reliably authenticating the server endpoint, so a rogue network peer can be accepted as the relay. An attacker must occupy an adjacent network path; interception can expose credentials and forge or interrupt traffic between the setup tool and relay.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
