Descriptions

A flaw was found in the use of insufficiently random values in Ansible. Two random password lookups of the same length generate the equal value as the template caching action for the same file since no re-evaluation happens. The highest threat from this vulnerability would be that all passwords are exposed at once for the file. This flaw affects Ansible Engine versions before 2.9.6.

Se encontró un fallo en el uso de valores insuficientemente aleatorios en Ansible. Dos búsquedas de contraseñas aleatorias de la misma longitud generan el mismo valor que la acción de almacenamiento en caché de la plantilla para el mismo archivo, ya que no se realiza una reevaluación. La mayor amenaza de esta vulnerabilidad sería que todas las contraseñas estén expuestas a la vez para el archivo. Este fallo afecta a Ansible Engine versiones anteriores a 2.9.6
