At a glance

CVE-2020-9454 is a high-severity Cross-Site Request Forgery (CSRF) vulnerability in the RegistrationMagic WordPress plugin, affecting versions < 4.6.0.4. It carries a CVSS score of 8.0 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). 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

A CSRF vulnerability in the RegistrationMagic plugin through 4.6.0.3 for WordPress allows remote attackers to forge requests on behalf of a site administrator to change all settings for the plugin, including deleting users, creating new roles with escalated privileges, and allowing PHP file uploads via forms.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed. 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 RegistrationMagic < 4.6.0.4 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 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?

The attempt arrives as an ordinary request to RegistrationMagic: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: RegistrationMagic 4.6.0.4 closes this, and updating the plugin is the step that ends it.
