Authenticated arbitrary file write via backslash traversal
Published Jul 15, 2026 · Updated Jul 15, 2026
Path traversal in FIT2CLOUD DataEase before 2.10.23 allows remote authenticated users to write arbitrary server files via template saves. StaticResourceServer.saveFilesToServe derives each destination name by searching only for '/', so backslash traversal remains in an attacker-controlled staticResource key while its paired Base64 value becomes file content. A low-privileged account with template-save access can place or overwrite files reachable by the service account, affecting integrity and availability without reported direct data disclosure.
