Descriptions

In OpenStack Murano through 16.0.0, when YAQL before 3.0.0 is used, the Murano service's MuranoPL extension to the YAQL language fails to sanitize the supplied environment, leading to potential leakage of sensitive service account information.

En OpenStack Murano hasta 16.0.0, cuando se utiliza YAQL anterior a 3.0.0, la extensión MuranoPL del servicio Murano para el lenguaje YAQL no logra sanitizar el entorno proporcionado, lo que genera una posible fuga de información confidencial de la cuenta de servicio.

A flaw was found in the Murano component of OpenStack. This vulnerability allows ordinary users capable of importing and deploying app packages to access sensitive information within OpenStack services. Specifically, through this exploit, unauthorized users can obtain Murano service account credentials, potentially escalating their privileges to an administrator level. Subsequently, unauthorized users can gain complete control over various resources, including user roles, hosts, and networks. The exploit allows access to the Murano service's oslo configuration storage, thereby exposing critical Murano service account credentials, and granting unauthorized users administrative privileges.

An update for python-yaql, openstack-tripleo-heat-templates, and openstack-tripleo-common is now available for Red Hat OpenStack Platform 16.2. Issues addressed include an information leakage vulnerability.
