Path-Traversal vulnerability in Revolution Pi version 2022-07-28-revpi-buster from KUNBUS GmbH. This vulnerability could allow an authenticated attacker to list device directories via the ‘/pictory/php/getFileList.php’ endpoint in the ‘dir’ parameter.
Solution:
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.
