Descriptions
Ansible before versions 2.3.1.0 and 2.4.0.0 fails to properly mark lookup-plugin results as unsafe. If an attacker could control the results of lookup() calls, they could inject Unicode strings to be parsed by the jinja2 templating system, resulting in code execution. By default, the jinja2 templating language is now marked as 'unsafe' and is not evaluated.
Ansible en versiones anteriores a la 2.3.1.0 y 2.4.0.0 no marca correctamente los resultados del plugin lookup como no seguros. Si un atacante pudiese controlar los resultados de las llamadas lookup(), podrían inyectar cadenas Unicode para que sean analizadas por el sistema de plantillas jinja2, resultando en una ejecución de código. Por defecto, el lenguaje de plantillas jinja2 se marca ahora como "no seguro" y no se evalúa.
An input validation flaw was found in Ansible, where it fails to properly mark lookup-plugin results as unsafe. If an attacker could control the results of lookup() calls, they could inject Unicode strings to be parsed by the jinja2 templating system, resulting in code execution. By default, the jinja2 templating language is now marked as 'unsafe' and is not evaluated.
