CVE-2023-39383Network attack vector

App-data disclosure via unvalidated AMS parameters

Published Aug 13, 2023 · Updated Oct 10, 2024

Improper input validation in affected Huawei HarmonyOS and EMUI releases allows remote attackers to read app data through crafted AMS parameters. Affected releases are HarmonyOS 2.0.0, 2.0.1, 2.1.0, 3.0.0, and 3.1.0 and EMUI 11.0.1, 12.0.0, 12.0.1, and 13.0.0; the AMS module does not strictly validate input parameters, but Huawei has not disclosed the specific parameters or downstream operation. Network reachability and no prior privileges or user interaction are required; the published impact is limited to app-data confidentiality.
