Official description

Multiple plugins and/or themes for WordPress are vulnerable to Arbitrary File Uploads due to a missing capability check on the ajaxUploadFonts() function in various versions. This makes it possible for authenticated attackers, with Subscriber-level access and above, to upload arbitrary files that can make remote code execution possible. This issue was escalated to Envato over two months from the date of this disclosure and the issue, while partially patched, is still vulnerable.

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.
