At a glance

This record tracks a high-severity Improper Privilege Management vulnerability in the wpCentral WordPress plugin, affecting versions < 1.4.8. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). The issue is fixed in version 1.4.8; sites on affected versions should update now. Disclosed January 2020, reported by WebARX Security.

Vulnerability Overview

The wpCentral for WordPress is vulnerable to privilege escalation in versions up to, and including, 1.4.7 due to missing authorization checks and validation on the wpc_fetch_authkey() and my_wpc_signon() functions. This makes it possible for authenticated users, with low-level privileges such as a subscriber, to log in as a site 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 interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-269: Improper Privilege Management

wpCentral < 1.4.8 carries this weakness at wpc_fetch_authkey(), and reaching it takes a caller who can reach the endpoint. 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 wpCentral the fix is 1.4.8: builds < 1.4.8 are affected, anything from 1.4.8 onward is not.

Remediation

Update to version 1.4.8, 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: wpCentral 1.4.8 closes this, and updating the plugin is the step that ends it.
