Vulnerability Overview

vars.php in WordPress 2.0.2, possibly when running on Mac OS X, allows remote attackers to spoof their IP address via a PC_REMOTE_ADDR HTTP header, which vars.php uses to redefine $_SERVER['REMOTE_ADDR'].

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 2.0.3, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to WordPress 2.0: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: updating to 2.0.3 is the step that ends it.
