An Authenticated Remote Code Exection (RCE) vulnerability exists in Xerte through 3.9 in website_code/php/import/fileupload.php by uploading a maliciously crafted PHP file though the project interface disguised as a language file to bypasses the upload filters. Attackers can manipulate the files destination by abusing path traversal in the 'mediapath' variable.
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.
