CVE-2022-29499 is a critical unauthenticated remote code execution vulnerability in the Service Appliance component of Mitel MiVoice Connect, affecting SA 100, SA 400, and Virtual SA deployments through 19.2 SP3, including earlier supported branches. The flaw is caused by insufficient or incorrect data validation in a diagnostic script, allowing a remote attacker to send specially crafted requests that inject commands for execution on the appliance. The issue has been described as arising from improper validation of attacker-controlled input in the appliance’s diagnostic functionality, enabling command injection and subsequent code execution in the context of the vulnerable system.
