Prior to version 4.5.3, Glances supports dynamic configuration values in which substrings enclosed in backticks are executed as system commands during configuration parsing. This behavior occurs in Config.get_value() and is implemented without validation or restriction of the executed commands. If an attacker can modify or influence configuration files, arbitrary commands will execute automatically with the privileges of the Glances process during startup or configuration reload. In deployments where Glances runs with elevated privileges (e.g., as a system service), this may lead to privilege escalation. This issue has been patched in version 4.5.3."}, {"lang": "es", "value": "Glances es una herramienta de monitoreo de sistema de c\u00f3digo abierto multiplataforma. Antes de la versi\u00f3n 4.5.3, Glances admite valores de configuraci\u00f3n din\u00e1micos en los que las subcadenas encerradas entre comillas invertidas se ejecutan como comandos del sistema durante el an\u00e1lisis de la configuraci\u00f3n. Este comportamiento ocurre en Config.get_value() y se implementa sin validaci\u00f3n ni restricci\u00f3n de los comandos ejecutados. Si un atacante puede modificar o influir en los archivos de configuraci\u00f3n, se ejecutar\u00e1n autom\u00e1ticamente comandos arbitrarios con los privilegios del proceso de Glances durante el inicio o la recarga de la configuraci\u00f3n. En implementaciones donde Glances se ejecuta con privilegios elevados (por ejemplo, como un servicio del sistema), esto puede conducir a una escalada de privilegios.
