CVE-2026-67247Network attack vector

Authenticated data disclosure via disk-serial path traversal

Published Jul 30, 2026 · Updated Jul 30, 2026

Path traversal in ASUSTOR Data Master allows remote authenticated users to read unintended files through the IHM Log handler. The handler uses a user-controlled disk serial to construct an IHM log database path without confining the resolved path to its intended directory. Low-privileged ADM access is sufficient on affected 4.1.0 through 4.3.3.RUN1 and 5.0.0 through 5.1.3.RI81 releases, exposing unintended filesystem or log database files.
