Vulnerability Overview

The FastDup – Fastest WordPress Migration & Duplicator plugin for WordPress is vulnerable to Path Traversal in all versions up to, and including, 2.7 via the 'dir_path' parameter in the 'njt-fastdup/v1/template/directory-tree' REST API endpoint. This makes it possible for authenticated attackers, with Contributor-level access and above, to read the contents of arbitrary directories on the server, which can contain sensitive information.

Technical Analysis

REMEDIATION: Update to version 2.7.1, 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.
