A vulnerability has been identified in GoldPanKit eva-server v4.1.0. It affects the path parameter of the /api/resource/local/download endpoint, where manipulation of this parameter can lead to arbitrary file download.
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
