Official description
The Avada | Website Builder For WordPress & WooCommerce theme for WordPress is vulnerable to Arbitrary File Upload in versions up to, and including, 7.16.2 via the convert_palette_images_to_truecolor() function. This is due to insufficient file type validation before processing uploaded files. This makes it possible for unauthenticated attackers to upload files that may be executable, which makes remote code execution possible.

The underlying weakness: Unrestricted Upload of File with Dangerous Type
The product allows the upload or transfer of dangerous file types that are automatically processed within its environment.
How developers prevent this class of flaw
- Generate a new, unique filename for an uploaded file instead of using the user-supplied filename, so that no external input is used at all.
- When the set of acceptable objects, such as filenames or URLs, is limited or known, create a mapping from a set of fixed input values (such as numeric IDs) to the actual filenames or URLs, and reject all other inputs.
- Consider storing the uploaded files outside of the web document root entirely. Then, use other mechanisms to deliver the files dynamically.
