Current Description

October/System is the system module for October CMS, a self-hosted CMS platform based on the Laravel PHP Framework. Prior to versions 1.0.476, 1.1.12, and 2.2.15, when the developer allows the user to specify their own filename in the `fromData` method, an unauthenticated user can perform remote code execution (RCE) by exploiting a race condition in the temporary storage directory. This vulnerability affects plugins that expose the `October\Rain\Database\Attach\File::fromData` as a public interface and does not affect vanilla installations of October CMS since this method is not exposed or used by the system internally or externally. The issue has been patched in Build 476 (v1.0.476), v1.1.12, and v2.2.15. Those who are unable to upgrade may apply with patch to their installation manually as a workaround.
