CVE-2024-21794Network attack vector

User redirection via login-page open redirect

Published Feb 1, 2024 · Updated Jun 16, 2025

Open redirect in Rapid SCADA 5.8.4 and earlier allows remote authenticated users to send users to malicious pages through the login page. Public disclosures do not identify the login-page parameter or validation error that permits an untrusted destination to control navigation. Exploitation requires low-privileged authentication and user interaction, enabling trusted-looking links to divert a user without reported direct data disclosure.
