An issue was discovered in Hyland OnBase through 18.0.0.32 and 19.x through 19.8.9.1000. Directory traversal exists for writing to files, as demonstrated by the FileName parameter.
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.
