At a glance

This record tracks a high-severity Cross-Site Request Forgery (CSRF) vulnerability in the Phone Orders for WooCommerce WordPress plugin, affecting versions <= 3.7.1. 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 3.7.2; sites on affected versions should update now. Disclosed October 2022.

Vulnerability Overview

The Phone Orders for WooCommerce plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 3.7.1. This is due to missing nonce validation on the ajax_gate function which controls many additional functions also missing nonce validation. This makes it possible for unauthenticated attackers to invoke this function and perform actions on behalf of administrators, via 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. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-352: Cross-Site Request Forgery (CSRF)

Reaching this weakness in Phone Orders for WooCommerce <= 3.7.1 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 Phone Orders for WooCommerce the fix is 3.7.2: builds <= 3.7.1 are affected, anything from 3.7.2 onward is not.

Remediation

Update to version 3.7.2, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Phone Orders for WooCommerce: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Phone Orders for WooCommerce 3.7.2 closes this, and updating the plugin is the step that ends it.
