Ray OS 2.6.3 Command Injection
The Ray Project dashboard contains a CPU profiling page, and the format parameter is not validated before being inserted into a system command executed in a shell, allowing for arbitrary command execution. If the system is configured to allow passwordless sudo (a setup some Ray configurations require) this will result in a root shell being returned to the user. If not configured, a user level shell will be returned. Versions 2.6.3 and below are affected.
