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.

The weakness was published 07/13/2022 as GHSA-8v7h-cpc2-r8jp. The advisory is available at github.com. This vulnerability is handled as CVE-2022-24800 since 02/10/2022. Technical details are known, but there is no available exploit.

Upgrading to version 1.0.476, 1.1.12 or 2.2.15 eliminates this vulnerability. Applying the patch fe569f3babf3f593be2b1e0a4ae0283506127a83 is able to eliminate this problem.
