At a glance

This record tracks a medium-severity Improper Input Validation vulnerability in the Store Exporter WordPress plugin, affecting versions <= 2.3.1. It carries a CVSS score of 6.0 (reachable over the network). The issue is fixed in version 2.4; sites on affected versions should update now. Disclosed January 2020, reported by Vishnupriya Ilango.

Vulnerability Overview

The WooCommerce - Store Exporter plugin for WordPress is vulnerable to CSV Injection in versions up to, and including, 2.3.1 via the Quick Export' functionality. This allows authenticated attackers to embed untrusted input into exported CSV files, which can result in code execution when these files are downloaded and opened on a local system with a vulnerable configuration.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, and no interaction from a victim user.

CWE-20: Improper Input Validation

Reaching this weakness in Store Exporter <= 2.3.1 takes a caller who can reach the endpoint. Improper input validation means the application accepts input without confirming it has the form, type or range the code downstream assumes.

The concrete impact depends on where the unvalidated value lands, which is why records in this class range from cosmetic bugs to full compromise. For Store Exporter the fix is 2.4: builds <= 2.3.1 are affected, anything from 2.4 onward is not.

Remediation

Update to version 2.4, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Store Exporter: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Store Exporter 2.4 closes this, and updating the plugin is the step that ends it.
