Privilege escalation via AMS input validation
Published Jun 13, 2022 · Updated Aug 3, 2024
Improper input validation in Huawei HarmonyOS 2.0 allows local users to gain privileges through the AMS module. Huawei identifies the AMS module as performing insufficient input verification, but does not disclose the specific interface, parameter, or faulty operation. Exploitation requires local access to a vulnerable device and results in unauthorized operations or privilege escalation.
