CVE-2025-24332

Cross-board access via unrevalidated internal SSH key

Published Jul 2, 2025 · Updated Jul 2, 2025

Authentication bypass in Nokia Single RAN AirScale before 23R4-SR 3.0 MP allows remote authenticated users to access all baseband boards. The internal bsoc SSH service accepts a private key stored on the system board when connecting to capacity boards without re-authenticating the user. Access requires a base-station administrative account within the MNO internal RAN management network; Internet, roaming-network, and user-equipment paths cannot reach the service.
