Vulnerability Overview

The Duplicator (Free & Pro) plugin for WordPress is vulnerable to Directory Traversal in versions up to 1.3.28 (and Duplicator Pro before 3.8.7.1) via the 'file' parameter through the duplicator_download() or duplicator_init() function. This makes it possible for unauthenticated attackers to read the contents of arbitrary files on the server, which can contain sensitive information.

Technical Analysis

REMEDIATION: Update to version 3.8.7.1, 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.
