CVE-2016-9599

puppet-tripleo, en versiones anteriores a la 5.5.0 y la 6.2.0, es vulnerable a un error de control de acceso en la gestión de reglas IPtables, que permite la creación de reglas TCP/UDP con valores de puerto vacíos. Si SSL está habilitado, un usuario malicioso podría emplear estos puertos abiertos para obtener acceso a recursos no autorizados.

puppet-tripleo is a key component of the Red Hat OpenStack Platform director, which is a toolset for installing and managing a complete OpenStack environment. Security Fix: An access-control flaw was discovered in puppet-tripleo's IPtables rules management, which allowed the creation of TCP/UDP rules with empty port values. Some API services in Red Hat OpenStack Platform director are not exposed to public networks, which meant their $public_ssl_port value was set to empty. If SSL was enabled, a malicious user could use these open ports to gain access to unauthorized resources.
