CVE-2023-39286Network attack vector

Configuration modification via forged web requests

Published Sep 14, 2023 · Updated Sep 25, 2024

Cross-site request forgery in Mitel MiVoice Connect Mobility Router 9.6.2307.103 and earlier allows remote attackers to modify system settings. Mitel identifies insufficient request validation for modified URLs but does not disclose the affected endpoint or validation check. Exploitation requires an authenticated user to load attacker-controlled content, and the resulting request can change configuration within that user's privileges.
