Technical details

An OS command injection vulnerability exists in Coolify's Livewire component 'Server\Resources'. The 'startUnmanaged', 'stopUnmanaged', and 'restartUnmanaged' methods accept a '$id' parameter from the browser and interpolate it directly into shell commands (e.g., 'docker stop -t 0 $id') executed via SSH on managed servers. Because the input lacks sanitization or shell escaping (such as escapeshellarg), an authenticated attacker can use command separators to execute arbitrary code with the privileges of the SSH user on the target server. The vulnerability is fixed in version 4.0.0-beta.471 by adding input validation patterns and proper shell argument escaping.
