CVE-2023-52544Network attack vector

Authenticated information disclosure via email path bypass

Published Apr 8, 2024 · Updated Nov 4, 2024

Path traversal in affected Huawei HarmonyOS and EMUI releases allows remote authenticated users to access confidential service data. The email module accepts file paths after its verification restriction is bypassed, but Huawei has not disclosed the affected API, path syntax, or exposed data. Exploitation requires low-privileged network access and no user interaction; the reported consequence is limited to confidentiality, with no integrity or availability impact.
