A Path Traversal vulnerability exists in TinyFileManager all version up to and including 2.4.6 that allows attackers to upload a file (with Admin credentials or with the CSRF vulnerability) with the "fullpath" parameter containing path traversal strings (../ and ..\) in order to escape the server's intended working directory and write malicious files onto any directory on the computer.
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.
