At a glance

This record tracks a critical-severity Incorrect User Management vulnerability in the Kadence Central WordPress plugin, affecting versions < 2.0.18. 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 2.0.18; sites on affected versions should update now. Disclosed October 2019.

Vulnerability Overview

The iThemes Sync plugin for WordPress is vulnerable to authentication bypass due to a missing validation on the secure key in versions up to, and including, 2.0.17. This makes it possible for unauthenticated attackers to add their own secure key leading to a complete compromise of the affected website.

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-286: Incorrect User Management

The product does not properly manage a user within its environment.

Remediation

Update to version 2.0.18, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: Kadence Central 2.0.18 closes this, and updating the plugin is the step that ends it.
