Sandbox file access via unchecked path parameter
Published Aug 13, 2023 · Updated Oct 9, 2024
Path traversal in the installd module of Huawei HarmonyOS and EMUI allows attackers to read and write sandbox files without authorization. The module accesses sandbox storage without adequately validating a pathname parameter, although Huawei has not disclosed the affected API or validation logic. CISA assesses network reachability without authentication; Huawei bounds the consequence to unauthorized sandbox-file reads and writes.
