Multiple relative path traversal vulnerabilities in the oneup/uploader-bundle before 1.9.3 and 2.1.5 allow remote attackers to upload, copy, and modify files on the filesystem (potentially leading to arbitrary code execution) via the (1) filename parameter to BlueimpController.php; the (2) dzchunkindex, (3) dzuuid, or (4) filename parameter to DropzoneController.php; the (5) qqpartindex, (6) qqfilename, or (7) qquuid parameter to FineUploaderController.php; the (8) x-file-id or (9) x-file-name parameter to MooUploadController.php; or the (10) name or (11) chunk parameter to PluploadController.php. This is fixed in versions 1.9.3 and 2.1.5.
The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize sequences such as ".." that can resolve to a location that is outside of that directory.
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.
