File access and privilege escalation via incorrect permissions
Published Aug 9, 2022 · Updated Sep 8, 2025
Incorrect permissions in Huawei's AOD module in EMUI 11.0.0 and 12.0.0 and HarmonyOS 2.0 allow attackers to read and write files. The module assigns directory permissions that permit unauthorized file access, but Huawei has not identified the affected path or the faulty permission-setting operation. CISA assesses network reachability with required user interaction; successful exploitation elevates privileges and exposes files to modification.
