CVE-2023-2948Public exploitNetwork attack vector

Victim-browser script execution via unescaped list identifier

Published May 28, 2023 · Updated Jan 14, 2025

Reflected XSS in OpenEMR before 7.0.1 allows remote attackers to execute script in a victim's browser via a crafted list_id value. The share_template.php handler writes list_id into a JavaScript data object with HTML escaping instead of JavaScript-context encoding. Exploitation requires a victim to open the crafted URL, after which script runs with the victim's OpenEMR browser-session privileges.
