Higher-privilege System Ability access via relay
Published Jan 9, 2023 · Updated Apr 9, 2025
Authentication bypass in OpenHarmony 3.0 through 3.0.5 allows local users to reach higher-privilege System Abilities through an SA relay attack. OpenHarmony identifies platform_callback_stub in the misc subsystem as the locus, but has not disclosed which authentication check mishandles the relayed call. Successful exploitation requires local low-privilege access and permits attacks against higher-privilege System Abilities; the exact accessible operations remain undisclosed.
