Vulnerability Overview

The MW WP Form plugin for WordPress is vulnerable to Directory Traversal in versions up to, and including, 4.4.2 via the _file_upload function. This allows unauthenticated attackers to upload files of allowed types to arbitrary directories on the site.

Technical Analysis

REMEDIATION: Update to version 4.4.3, or a newer patched version --- IDENTIFIER: CWE-22 (Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')) The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
