Vulnerability Overview

The User Meta WordPress plugin before 2.4.4 does not validate the filepath parameter of its um_show_uploaded_file AJAX action, which could allow low privileged users such as subscriber to enumerate the local files on the web server via path traversal payloads

Technical Analysis

REMEDIATION: Update to version 2.4.4, 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.
