Vulnerability Overview

The WP User Frontend plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the 'wpuf_file_upload' and 'wpuf_insert_image' AJAX actions in versions before 2.3.11. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected sites server which may make remote code execution possible.

Technical Analysis

REMEDIATION: Update to version 2.3.11, 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.
