At a glance

This record tracks a critical-severity Improper Authentication vulnerability in the Ultimate Addons for Elementor WordPress plugin, affecting versions < 1.20.1. 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 1.20.1; sites on affected versions should update now. Disclosed December 2019, reported by MalCare.

Vulnerability Overview

The Ultimate Addons for Elementor plugin for WordPress is vulnerable to authorization bypass due to a missing capability check when logging in by Google or Facebook in versions up to, and including, 1.20.0. This makes it possible for attackers to authenticate as any other user, including an administrator.

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-287: Improper Authentication

Reaching this weakness in Ultimate Addons for Elementor < 1.20.1 takes a caller who can reach the endpoint. Improper authentication means the mechanism that proves who a caller is can be satisfied without the secret it was supposed to require.

An attacker authenticates as another user — administrators included — without ever knowing a password, so password policies and login rate limits never come into play. For Ultimate Addons for Elementor the fix is 1.20.1: builds < 1.20.1 are affected, anything from 1.20.1 onward is not.

Remediation

Update to version 1.20.1, 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: Ultimate Addons for Elementor 1.20.1 closes this, and updating the plugin is the step that ends it.
