osClass 3.6.1 allows oc-admin/plugins.php Directory Traversal via the plugin parameter. This is exploitable for remote PHP code execution because an administrator can upload an image that contains PHP code in the EXIF data via index.php?page=ajax&action=ajax_upload.
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.
