At a glance

CVE-2020-9458 is a medium-severity Missing Authorization vulnerability in the RegistrationMagic WordPress plugin, affecting versions < 4.6.0.4. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires an authenticated account. The issue is fixed in version 4.6.0.4; sites on affected versions should update now. Disclosed March 2020, reported by Ram.

Vulnerability Overview

In the RegistrationMagic plugin through 4.6.0.3 for WordPress, the export function allows remote authenticated users (with minimal privileges) to export submitted form data and settings via class_rm_form_controller.php rm_form_export.

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.

CWE-862: Missing Authorization

Reaching this weakness in RegistrationMagic < 4.6.0.4 takes any authenticated account. 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 RegistrationMagic the fix is 4.6.0.4: builds < 4.6.0.4 are affected, anything from 4.6.0.4 onward is not.

Remediation

Update to version 4.6.0.4, 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: RegistrationMagic 4.6.0.4 closes this, and updating the plugin is the step that ends it.
