The Glances action system allows administrators to configure shell commands that execute when monitoring thresholds are exceeded. These commands support Mustache template variables (e.g., `{{name}}`, `{{key}}`) that are populated with runtime monitoring data. The `secure_popen()` function, which executes these commands, implements its own pipe, redirect, and chain operator handling by splitting the command string before passing each segment to `subprocess.Popen(shell=False)`. Prior to 4.5.2, when a Mustache-rendered value (such as a process name, filesystem mount point, or container name) contains pipe, redirect, or chain metacharacters, the rendered command is split in unintended ways, allowing an attacker who controls a process name or container name to inject arbitrary commands. Version 4.5.2 fixes the issue."}, {"lang": "es", "value": "Glances es una herramienta de monitoreo de sistema multiplataforma de c\u00f3digo abierto. El sistema de acciones de Glances permite a los administradores configurar comandos de shell que se ejecutan cuando se superan los umbrales de monitoreo. Estos comandos admiten variables de plantilla Mustache (por ejemplo, `{{name}}`, `{{key}}`) que se rellenan con datos de monitoreo en tiempo de ejecuci\u00f3n. La funci\u00f3n `secure_popen()`, que ejecuta estos comandos, implementa su propio manejo de operadores de tuber\u00eda (pipe), redirecci\u00f3n y encadenamiento dividiendo la cadena de comando antes de pasar cada segmento a `subprocess.Popen(shell=False)`. Antes de la versi\u00f3n 4.5.2, cuando un valor renderizado por Mustache (como un nombre de proceso, un punto de montaje del sistema de archivos o un nombre de contenedor) contiene metacaracteres de tuber\u00eda (pipe), redirecci\u00f3n o encadenamiento, el comando renderizado se divide de formas no intencionadas, permitiendo a un atacante que controla un nombre de proceso o un nombre de contenedor inyectar comandos arbitrarios.
