CVE-2025-0970Public exploitNetwork attack vector

User redirection via unchecked ReturnUrl destination

Published Feb 2, 2025 · Updated Feb 12, 2025

Open redirect in Zenvia Movidesk 25.01.22 and earlier allows remote attackers to send users to an external site via a crafted login URL. The /Account/Login handler accepts a protocol-relative //evil.com value in ReturnUrl and uses it as the redirect destination without restricting external sites. No authentication is required to create the URL, but exploitation requires a user to follow it; the resulting redirection can support phishing.
