At a glance

CVE-2022-2552 is a high-severity Exposure of Sensitive Information to an Unauthorized Actor vulnerability in the Duplicator WordPress plugin, affecting versions <= 1.4.7. It carries a CVSS score of 7.5 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires no authentication. The issue is fixed in version 1.4.7.1; sites on affected versions should update now. Disclosed July 2022, reported by SecuriTrust.

Vulnerability Overview

The Duplicator – WordPress Migration Plugin WordPress plugin is vulnerable to Unauthenticated System Information Disclosure in versions up to, and including, 1.4.7 via the 'view' or 'debug' parameter. This allows an unauthenticated attacker to obtain sensitive configuration information about the vulnerable system which includes details like PHP Version, Operating System, Full Path and more. This requires that the installer script has been run at least once by a site owner/administrator.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user. A successful exploit has high impact on confidentiality.

CWE-200: Exposure of Sensitive Information to an Unauthorized Actor

Duplicator <= 1.4.7 carries this weakness at view, and reaching it takes a caller who can reach the endpoint. Sensitive information exposure means data the application intended to keep internal is returned to a caller who should not be able to see it.

The disclosed data — credentials, tokens, customer records or internal paths — is usually worth more as material for a follow-up attack than as an end in itself. For Duplicator the fix is 1.4.7.1: builds <= 1.4.7 are affected, anything from 1.4.7.1 onward is not.

Remediation

Update to version 1.4.7.1, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: Duplicator 1.4.7.1 closes this, and updating the plugin is the step that ends it.
