Open redirect in Zucchetti Ad Hoc Infinity 2.4 allows attackers to send authenticated users to a phishing site through a crafted login URL. The login page rejects m_cURL values beginning with HTTP schemes but copies scheme-relative values beginning with // unchanged into the Location response header.
