At a glance

CVE-2020-12074 is a high-severity Missing Authorization vulnerability in the Export and Import Users and Customers WordPress plugin, affecting versions < 1.3.9. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). The issue is fixed in version 1.3.9; sites on affected versions should update now. Disclosed March 2020, reported by Chloe Chamberland.

Vulnerability Overview

The users-customers-import-export-for-wp-woocommerce plugin (and other Webtoffee plugins) before 1.3.9 for WordPress allows subscribers to import administrative accounts via CSV.

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. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-862: Missing Authorization

Reaching this weakness in Export and Import Users and Customers < 1.3.9 takes a caller who can reach the endpoint. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.

Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For Export and Import Users and Customers the fix is 1.3.9: builds < 1.3.9 are affected, anything from 1.3.9 onward is not.

Remediation

Update to version 1.3.9, or a newer patched version

How does WordSec protect against this?

Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: Export and Import Users and Customers 1.3.9 closes this, and updating the plugin is the step that ends it.
