Description

A flaw has been found in oretnom23 file-management-system-php up to 2e3c1ebe60f121e8df4fb3f544f0e9591d9a01e4. This affects the function save_files of the file admin_class.php. Executing a manipulation of the argument Upload can lead to unrestricted upload. It is possible to launch the attack remotely. The exploit has been published and may be used. This product takes the approach of rolling releases to provide continious delivery. Therefore, version details for affected and updated releases are not available. The project was informed of the problem early through an issue report but has not responded yet.
