At a glance

CVE-2013-2694 is a medium-severity URL Redirection to Untrusted Site ('Open Redirect') vulnerability in the WP Symposium WordPress plugin, affecting versions <= 13.04.

Vulnerability Overview

Open redirect vulnerability in invite.php in the WP Symposium plugin 13.04 for WordPress allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via a URL in the u parameter.

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.

CWE-601: URL Redirection to Untrusted Site ('Open Redirect')

Reaching this weakness in WP Symposium <= 13.04 takes a caller who can reach the endpoint. An open redirect is a page that takes a destination from the request and sends the browser there without checking that the destination belongs to the site.

A link that starts on a trusted domain finishes on an attacker's, which is what makes phishing and consent-screen abuse credible to the person clicking it. For WP Symposium the fix is 13.05: builds <= 13.04 are affected, anything from 13.05 onward is not.

Remediation

Update to version 13.05, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to WP Symposium: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: WP Symposium 13.05 closes this, and updating the plugin is the step that ends it.
