Vulnerability Overview

The Download Monitor plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation and access controls on the 'upload_file' function in versions up to, and including, 4.8.3. This makes it possible for authenticated attackers with subscriber-level capabilities or above to upload arbitrary files on the affected site's server which may make remote code execution possible.

Technical Analysis

REMEDIATION: Update to version 4.8.4, or a newer patched version --- IDENTIFIER: CWE-434 (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.
