Official description

The Realtyna Organic IDX plugin + WPL Real Estate WordPress plugin before 5.3.0 does not validate the type of uploaded files, and its file upload functionality is gated only by an API that is enabled by default and authenticated with hardcoded credentials shipped identically across all installations. This makes it possible for unauthenticated attackers to upload arbitrary PHP files and achieve remote code execution.

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.
