# AzuraCast: timezone field lets station managers run commands as root

AzuraCast, a web radio hosting panel, accepts newlines in the station timezone field, which lets a station manager inject a Supervisor program definition. When the configuration regenerates, that program runs operating system commands as root.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the AzuraCast version with the installed release tag; the sources say the issue affects `0.23.8` and earlier.
- List station manager accounts and review who can edit station profiles.

## Fix

- Move AzuraCast past `0.23.8`; the sources do not name the exact fixed release.

## From the sources

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.
