CVE-2024-11304Public exploitNetwork attack vector

Browser script execution via unvalidated stored settings

Published Nov 18, 2024 · Updated Nov 21, 2024

Stored XSS in SEH utnserver Pro, utnserver ProMAX, and INU-100 20.1.22 and earlier allows remote authenticated users to run scripts. The web interface stores unvalidated script input in usrMg_pwd, usbMdg_pwd, certificate identity fields, and device-description fields, then renders it as executable page content. An attacker needs access to change device settings, and the payload runs when another user opens the affected configuration or information view in a browser.
