A directory traversal vulnerability exists in core\admin\ajax\developer\extensions\file-browser.php in BigTree CMS through 4.2.18 on Windows, allowing attackers to read arbitrary files via ..\ sequences in the directory 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.
