If exploited, this absolute path traversal vulnerability could allow attackers to traverse files in File Station. QNAP has already fixed these issues in QES 2.1.1 Build 20201006 and later.
Solution:
The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
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.
