At a glance

CVE-2021-24158 is a critical-severity Improper Privilege Management vulnerability in the Orbit Fox WordPress plugin, affecting versions < 2.10.3. It carries a CVSS score of 9.9 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires an authenticated account. The issue is fixed in version 2.10.3; sites on affected versions should update now. Disclosed November 2020, reported by Chloe Chamberland.

Vulnerability Overview

Orbit Fox by ThemeIsle has a feature to add a registration form to both the Elementor and Beaver Builder page builders functionality. As part of the registration form, administrators can choose which role to set as the default for users upon registration. This field is hidden from view for lower-level users, however, they can still supply the user_role parameter to update the default role for registration.

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. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-269: Improper Privilege Management

Reaching this weakness in Orbit Fox < 2.10.3 takes any authenticated account. Improper privilege management means the code lets an account end up with capabilities its role should not have.

It converts a low-privileged account into an administrative one, which makes every other restriction on the site irrelevant. For Orbit Fox the fix is 2.10.3: builds < 2.10.3 are affected, anything from 2.10.3 onward is not.

Remediation

Update to version 2.10.3, 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: Orbit Fox 2.10.3 closes this, and updating the plugin is the step that ends it.
