At a glance
This record tracks a high-severity URL Redirection to Untrusted Site ('Open Redirect') vulnerability in the Grimag WordPress theme, affecting versions <= 1.1.0. It carries a CVSS score of 7.2 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 1.1.1; sites on affected versions should update now. Disclosed June 2014.
Vulnerability Overview
The Grimag theme for WordPress is vulnerable to Open Redirect in versions up to, and including, 1.1.0 via the 'go.php' file. This makes it possible for unauthenticated attackers to redirect users to a potentially malicious website where they can gather sensitive user information for future attacks.
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-601: URL Redirection to Untrusted Site ('Open Redirect')
Reaching this weakness in Grimag <= 1.1.0 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 Grimag the fix is 1.1.1: builds <= 1.1.0 are affected, anything from 1.1.1 onward is not.
Remediation
Update to version 1.1.1, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Grimag: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Grimag 1.1.1 closes this, and updating the theme is the step that ends it.
