Senserva AI Opinion for CVE-2022-41223

The Director component of Mitel MiVoice Connect allows an authenticated attacker on the internal network to execute code within the application. Its Medium CVSS of 6.8 hides the operational reality: VoIP appliances are rarely monitored or patched, and ransomware groups have used this flaw to persist quietly inside networks after gaining initial access. It has been in CISA KEV since February 2023.

Do this: Update MiVoice Connect systems and put voice infrastructure on a separate VLAN with restricted management access.
