Vulnerability Overview

The MailChimp Subscribe Forms plugin for WordPress is vulnerable to Open Redirect in versions up to, and including, 4.0.9.3. This is due to the application failing to properly verify a user-supplied input parameter. This makes it possible for unauthenticated attackers to exploit this issue and redirect users to arbitrary web sites and conduct phishing attacks; other attacks are also possible.

Technical Analysis

REMEDIATION: Update to version 4.0.9.4, or a newer patched version --- IDENTIFIER: CWE-601 (URL Redirection to Untrusted Site ('Open Redirect')) The web application accepts a user-controlled input that specifies a link to an external site, and uses that link in a redirect.
