Affected by this issue is some unknown functionality of the file tinyfilemanager.php of the component Remote URL File Upload Module. The manipulation leads to unrestricted upload. It is possible to initiate the attack remotely. The exploit has been disclosed publicly and may be used. The vendor was contacted early about this disclosure but did not respond in any way.","summary":"TinyFileManager, a single-file PHP web file manager, has an unrestricted upload flaw in its Remote URL File Upload module in tinyfilemanager.php.
