CVE-2023-44093Network attack vector

Service data disclosure via unverified package keys

Published Oct 11, 2023 · Updated Sep 18, 2024

Authentication failure in Huawei HarmonyOS and EMUI allows remote attackers to disclose service data via crafted package identities. The security module accepts package-name public keys without verifying them, so a crafted package identity can be treated as trusted. The issue is reachable over a network without privileges or user interaction and affects 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.
