AzuraCast through 0.23.8 RCE via Supervisor Configuration Injection in Timezone

Summary

AzuraCast through 0.23.8 contains a remote code execution vulnerability that allows authenticated station managers to inject Supervisor configuration through the station timezone field. Attackers can submit a timezone containing newlines to the profile edit API, defining a new Supervisor program that executes OS commands as root when configuration regenerates.
