At a glance

CVE-2016-10935 is a critical-severity Missing Authorization vulnerability in the Store Exporter WordPress plugin, affecting versions < 1.8.4. It carries a CVSS score of 9.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 1.8.4; sites on affected versions should update now. Disclosed February 2016, reported by James Golovich.

Vulnerability Overview

The WooCommerce – Store Exporter plugin for WordPress is vulnerable to authorization bypass due to a missing capability check in the woo_ce_admin_init function hooked via 'init' in versions up to, and including 1.8.3. This makes it possible for unauthenticated attackers to perform actions like exporting data that may contain sensitive information.

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, 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

Store Exporter < 1.8.4 carries this weakness at init, and reaching it 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 Store Exporter the fix is 1.8.4: builds < 1.8.4 are affected, anything from 1.8.4 onward is not.

Remediation

Update to version 1.8.4, 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: Store Exporter 1.8.4 closes this, and updating the plugin is the step that ends it.
