Vulnerability Overview

WordPress before 3.7.5, 3.8.x before 3.8.5, 3.9.x before 3.9.3, and 4.x before 4.0.1 might allow remote attackers to obtain access to an account idle since 2008 by leveraging an improper PHP dynamic type comparison for an MD5 hash.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, 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-916: Use of Password Hash With Insufficient Computational Effort

The product generates a hash for a password, but it uses a scheme that does not provide a sufficient level of computational effort that would make password cracking attacks infeasible or expensive.

Remediation

Update to one of the following versions, or a newer patched version: 3.7.5, 3.8.5, 3.9.3, 4.0.1

How does WordSec protect against this?

The fix is the thing that ends this: updating to 3.7.5 is the step that ends it.
