Vulnerability Overview

The Active Directory Integration / LDAP Integration plugin for WordPress is vulnerable to LDAP Passback in versions up to, and including, 4.1.10. This is due to insufficient validation when changing the LDAP server. This makes it possible for authenticated attackers, with administrative access and above, to change the LDAP server and retrieve the credentials for the original LDAP server.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, and no interaction from a victim user.

CWE-306: Missing Authentication for Critical Function

The product does not perform any authentication for functionality that requires a provable user identity or consumes a significant amount of resources.

Remediation

Update to version 4.2, 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: Active Directory Integration / LDAP Integration 4.2 closes this, and updating the plugin is the step that ends it.
