Vulnerability Overview

The WordPress Download Manager plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the wpdm_admin_upload_file function in versions before 3.1.19. Dangerous extensions such as .php4 are not restricted. This makes it possible for authenticated attackers with Author-level privileges and above to upload arbitrary files on the affected sites server which may make remote code execution possible.

Technical Analysis

REMEDIATION: Update to version 3.1.19, 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.
