Overview   The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize '.../...//' (doubled triple dot slash) sequences that can resolve to a location that is outside of that directory. (CWE-35)   Description   Hitachi Vantara Pentaho Data Integration & Analytics versions before 10.2.0.2, including 9.3.x and 8.3.x, do not sanitize a user input used as a file path through the UploadFile service.   Impact   This allows attackers to traverse the file system to access files or directories that are outside of the restricted directory.
