CVE-2023-25599Network attack vector

Script execution via insufficiently validated presenter input

Published May 24, 2023 · Updated Jan 16, 2025

Reflected XSS in Mitel MiVoice Connect 19.3 SP2 and earlier allows remote attackers to execute scripts via test_presenter.php. The conferencing component's test_presenter.php page insufficiently validates request input before reflecting it into a response interpreted by the browser as script. Exploitation requires user interaction with an attacker-crafted request, and execution is confined to the affected site's browser context.
