At a glance
This record tracks a high-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Conversion Tracking for WooCommerce WordPress plugin, affecting versions < 2.0.5. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 2.0.6; sites on affected versions should update now. Disclosed January 2020.
Vulnerability Overview
The WooCommerce Conversion Tracking plugin for WordPress is vulnerable to Cross-Site Request Forgery and Cross-Site Scripting in versions up to, and including, 2.0.4 due to insufficient input sanitization and output escaping along with insufficient nonce validation on the wcct_save_settings() function. This makes it possible for attackers to inject arbitrary web scripts that execute in a victim's browser via a forged request.
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. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.
CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Conversion Tracking for WooCommerce < 2.0.5 carries this weakness at wcct_save_settings(), 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 Conversion Tracking for WooCommerce the fix is 2.0.6: builds < 2.0.5 are affected, anything from 2.0.6 onward is not.
Remediation
Update to version 2.0.6, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Conversion Tracking for WooCommerce: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Conversion Tracking for WooCommerce 2.0.6 closes this, and updating the plugin is the step that ends it.
