Vulnerability Overview

The Maintenance Mode plugin for WordPress is vulnerable to IP Address Spoofing in all versions up to, and including, 3.0.1 due to insufficient IP address validation. This makes it possible for unauthenticated attackers to spoof their IP Address.

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.

CWE-348: Use of Less Trusted Source

The product has two different sources of the same data or information, but it uses the source that has less support for verification, is less trusted, or is less resistant to attack.

Remediation

Update to version 3.0.2, or a newer patched version

How does WordSec protect against this?

Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Maintenance Mode 3.0.2 closes this, and updating the plugin is the step that ends it.
