CVE-2023-30621

Estado: ModificadaCrítica (9.8)—

Gipsy es un bot de Discord de uso múltiple que pretende ser lo más modular y fácil de usar posible. En versiones anteriores a la 1.3, los usuarios pueden ejecutar comandos en la máquina host con permisos de sudoer. El comando `!ping`, cuando se le proporciona una IP o un nombre de host, ejecutaba un `ping <IP>` en bash sin verificar que la IP o el nombre de host fueran legítimos. Este comando se ejecutaba con permisos de root y puede dar lugar a la inyección de comandos arbitrarios en el servidor host. Se recomienda a los usuarios actualizar. No se conocen soluciones alternativas para esta vulnerabilidad.
