At a glance

CVE-2023-2487 is a medium-severity Exposure of Sensitive Information to an Unauthorized Actor vulnerability in the Export All Posts, Products, Orders & Users WordPress plugin, affecting versions <= 2.4.1. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 2.4.2; sites on affected versions should update now. Disclosed October 2023, reported by Jonas Höbenreich.

Vulnerability Overview

The WP Ultimate Exporter plugin for WordPress is vulnerable to Sensitive Information Exposure in versions up to, and including, 2.4.1 due to insufficient protection on the directory in which exported files are stored in. This can allow unauthenticated attackers to extract sensitive data from accessible log files which can contain information from posts, pages, users, comments, and more. CVE-2023-45066 appears to be a duplicate of this issue.

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.

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

Reaching this weakness in Export All Posts, Products, Orders & Users <= 2.4.1 takes no account at all. 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 Export All Posts, Products, Orders & Users the fix is 2.4.2: builds <= 2.4.1 are affected, anything from 2.4.2 onward is not.

Remediation

Update to version 2.4.2, or a newer patched version

How does WordSec protect against this?

This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: Export All Posts, Products, Orders & Users 2.4.2 closes this, and updating the plugin is the step that ends it.
