Descriptions

Red Hat CloudForms Management Engine 4.1 does not properly handle regular expressions passed to the expression engine via the JSON API and the web-based UI, which allows remote authenticated users to execute arbitrary shell commands by leveraging the ability to view and filter collections.

Red Hat CloudForms Management Engine 4.1 no maneja adecuadamente expresiones regulares pasadas al motor de expresión a través de la API JSON y la interfaz de usuario basada en web, lo que permite a usuarios remotos autenticados ejecutar comandos shell arbitrarios aprovechando la capacidad de ver y filtrar colecciones.

An input validation flaw was found in the way CloudForms regular expressions were passed to the expression engine via both the JSON API and the web based UI. A user with the ability to view collections and filter them could use this flaw to execute arbitrary shell commands on the host with the privileges of the CloudForms process.
