At a glance
CVE-2018-11485 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Advance Search for WooCommerce WordPress plugin, affecting versions < 1.1. It carries a CVSS score of 6.1 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 1.1; sites on affected versions should update now. Disclosed May 2018, reported by ThreatPress.
Vulnerability Overview
The MULTIDOTS WooCommerce Quick Reports plugin 1.0.6 and earlier for WordPress is vulnerable to Stored XSS. It allows an attacker to inject malicious JavaScript code on the WooCommerce -> Orders admin page. The attack is possible by modifying the "referral_site" cookie to have an XSS payload, and placing an order.
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.
CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Advance Search for WooCommerce < 1.1 carries this weakness at referral_site, 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 Advance Search for WooCommerce the fix is 1.1: builds < 1.1 are affected, anything from 1.1 onward is not.
Remediation
Update to version 1.1, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Advance Search for WooCommerce: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Advance Search for WooCommerce 1.1 closes this, and updating the plugin is the step that ends it.
