Vulnerability from fkie_nvd - Published: 2026-03-18 07:16 - Updated: 2026-03-18 18:27
Severity ?
7.0 (High) - CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
Glances is an open-source system cross-platform monitoring tool. 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.

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. La versi\u00f3n 4.5.2 corrige el problema."
