At a glance

This record tracks a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Store Exporter WordPress plugin, affecting versions <= 1.7.5. It carries a CVSS score of 6.4 (reachable over the network; low attack complexity). The issue is fixed in version 1.7.6; sites on affected versions should update now. Disclosed August 2014, reported by Mike Manzotti.

Vulnerability Overview

The WooCommerce – Store Exporter plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'export_filename' parameter in versions up to, and including, 1.7.5 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers to inject arbitrary web scripts that execute in a victim's browser.

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 interaction from a victim user.

CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Store Exporter <= 1.7.5 carries this weakness at export_filename, and reaching it takes a caller who can reach the endpoint. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.

Injected script runs with the privileges of whoever views the affected page, which is how these flaws turn into administrator session theft, silent account creation or persistent backdoors in page content. For Store Exporter the fix is 1.7.6: builds <= 1.7.5 are affected, anything from 1.7.6 onward is not.

Remediation

Update to version 1.7.6, 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 1.7.6 closes this, and updating the plugin is the step that ends it.
