Local high-privilege SA access via authentication relay
Published Jan 9, 2023 · Updated Apr 9, 2025
Authentication bypass in OpenHarmony 3.0 through 3.0.5 allows local users to access high-privilege SAs through an SA relay attack. The published record identifies softbus_client_stub as the locus and an SA relay as the bypass, but does not disclose the erroneous check or operation. A low-privileged local user can cross the SA privilege boundary and obtain information exposed by higher-privilege SAs; the CNA reports no integrity or availability impact.
