At a glance
This record tracks a critical-severity Incorrect Privilege Assignment vulnerability in the ConvertPlus WordPress plugin, affecting versions < 3.4.3. 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 3.4.3; sites on affected versions should update now. Disclosed May 2019, reported by Mikey Veenstra.
Vulnerability Overview
The ConvertPlug plugin for WordPress is vulnerable to Unauthenticated Administrator Creation in versions up to, and including, 3.4.2. This is due to insufficient validation on role selection during user registeration. This makes it possible for unauthenticated attackers to register as administrators on vulnerable sites.
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-266: Incorrect Privilege Assignment
A product incorrectly assigns a privilege to a particular actor, creating an unintended sphere of control for that actor.
Remediation
Update to version 3.4.3, or a newer patched version
How does WordSec protect against this?
This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: ConvertPlus 3.4.3 closes this, and updating the plugin is the step that ends it.
