CVE-2023-1693Network attack vector

Unauthenticated data disclosure via file privilege escalation

Published May 20, 2023 · Updated Jan 21, 2025

File privilege escalation in Huawei EMUI 11.0.1 and 13.0.0 and HarmonyOS 3.1.0 allows remote attackers to disclose data. Huawei's public advisories do not identify the affected file, entry point, or incorrect privilege operation in the Settings module. No authentication or user interaction is required, and the published impact is limited to confidentiality rather than data modification or service interruption.
