CVE-2025-35034Network attack vector

Victim-browser script execution via portlet_user_id reflection

Published Sep 29, 2025 · Updated Sep 29, 2025

Reflected cross-site scripting in Medical Informatics Engineering Enterprise Health allows remote attackers to execute JavaScript via a crafted URL. The portlet_user_id URL parameter is reflected into a generated page without neutralizing script-capable input, causing the victim's browser to interpret attacker-controlled markup as active content. No account is required, but a victim must open the crafted URL; execution is confined to the victim's browser context and can alter page content or actions.
