At a glance
CVE-2023-39158 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the Banner Management For WooCommerce WordPress plugin, affecting versions <= 2.4.1. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 2.4.3; sites on affected versions should update now. Disclosed July 2023, reported by Kévin Mosbahi (Mika).
Vulnerability Overview
The Woocommerce Category Banner Management plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 2.4.1. This is due to missing nonce validation on the wcbm_save_shop_page_banner_data() function. This makes it possible for unauthenticated attackers to invoke this function and update shop banner page data via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
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-352: Cross-Site Request Forgery (CSRF)
Banner Management For WooCommerce <= 2.4.1 carries this weakness at wcbm_save_shop_page_banner_data(), and reaching it takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.
An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For Banner Management For WooCommerce the fix is 2.4.3: builds <= 2.4.1 are affected, anything from 2.4.3 onward is not.
Remediation
Update to version 2.4.3, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Banner Management For WooCommerce: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Banner Management For WooCommerce 2.4.3 closes this, and updating the plugin is the step that ends it.
