CVE-2017-7481

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.

Red Hat OpenShift Container Platform is the company's cloud computing Platform-as-a-Service solution designed for on-premise or private cloud deployments. Ansible is a SSH-based configuration management, deployment, and task execution system. The openshift-ansible packages contain Ansible code and playbooks for installing and upgrading OpenShift Container Platform 3. Security Fix: An input validation vulnerability was found in Ansible's handling of data sent from client systems. An attacker with control over a client system being managed by Ansible, and the ability to send facts back to the Ansible server, could use this flaw to execute arbitrary code on the Ansible server using the Ansible server privileges.
