Summary
October CMS upload process vulnerable to RCE via Race Condition
Details

Impact

This advisory affects plugins that expose the October\Rain\Database\Attach\File::fromData as a public interface. This vulnerability does not affect vanilla installations of October CMS since this method is not exposed or used by the system internally or externally.

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.

Patches

The issue has been patched in Build 476 (v1.0.476) and v1.1.12 and v2.2.15.

Workarounds

Apply https://github.com/octobercms/library/commit/fe569f3babf3f593be2b1e0a4ae0283506127a83 to your installation manually if unable to upgrade to Build 476 (v1.0.476) or v1.1.12 or v2.2.15.
