Prior to 1.13.0, Arcane has a command injection in the updater service. Arcane\u2019s updater service supported lifecycle labels com.getarcaneapp.arcane.lifecycle.pre-update and com.getarcaneapp.arcane.lifecycle.post-update that allowed defining a command to run before or after a container update. The label value is passed directly to /bin/sh -c without sanitization or validation. Because any authenticated user (not limited to administrators) can create projects through the API, an attacker can create a project that specifies one of these lifecycle labels with a malicious command. When an administrator later triggers a container update (either manually or via scheduled update checks), Arcane reads the lifecycle label and executes its value as a shell command inside the container. This vulnerability is fixed in 1.13.0."}, {"lang": "es", "value": "Arcane proporciona gesti\u00f3n moderna de Docker. Antes de 1.13.0, Arcane tiene una inyecci\u00f3n de comandos en el servicio de actualizaci\u00f3n. El servicio de actualizaci\u00f3n de Arcane soportaba etiquetas de ciclo de vida com.getarcaneapp.arcane.lifecycle.pre-update y com.getarcaneapp.arcane.lifecycle.post-update que permit\u00edan definir un comando para ejecutar antes o despu\u00e9s de una actualizaci\u00f3n de contenedor. El valor de la etiqueta se pasa directamente a /bin/sh -c sin saneamiento ni validaci\u00f3n.
