Vulnerability Overview

The Duplicator WordPress Plugin is vulnerable to Unauthenticated Backup Download in versions up to, and including, 1.4.7 via the 'is_daws' parameter due to the fact that the source code of the response contains the randomized filename related to the back-up file that also exists in the same directory. This makes it possible for an unauthenticated attacker to download a full site backup which may contain sensitive information. This requires that the installer script has been run at least once by a site owner/administrator.

Technical Analysis

REMEDIATION: Update to version 1.4.7.1, or a newer patched version --- IDENTIFIER: CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor) The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
