File disclosure via backslash path traversal
Published Sep 14, 2026 · Updated Sep 14, 2026
Path traversal in StaticResourceController in FIT2CLOUD DataEase 1.18.9 and earlier allows remote attackers to read server files. The controller keeps the substring after the last forward slash but passes backslash dot-segments to the Windows filesystem without equivalent normalization. The flaw is reachable over the web interface only when DataEase runs on Windows, where it exposes files readable by the service, including application configuration.
