Vulnerability Overview

The Woffice Core plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 5.4.30 due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to [describe the impact of the vulnerability].

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.

CWE-639: Authorization Bypass Through User-Controlled Key

Reaching this weakness in Woffice Core <= 5.4.30 takes no account at all. Authorization bypass through a user-controlled key, often called insecure direct object reference, means the application looks up a record by an identifier from the request without checking that the caller owns it.

Changing a number in the request is enough to read or modify other users' records, which on commerce and membership sites means customer data. For Woffice Core the fix is 5.4.31: builds <= 5.4.30 are affected, anything from 5.4.31 onward is not.

Remediation

Update to version 5.4.31, or a newer patched version

How does WordSec protect against this?

This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: Woffice Core 5.4.31 closes this, and updating the plugin is the step that ends it.
