Descriptions

This vulnerability allows authenticated users with produce or consume permissions to perform unauthorized operations on partitioned topics, such as unloading topics and triggering compaction. These management operations should be restricted to users with the tenant admin role or superuser role. An authenticated user with produce permission can create subscriptions and update subscription properties on partitioned topics, even though this should be limited to users with consume permissions. This impact analysis assumes that Pulsar has been configured with the default authorization provider. For custom authorization providers, the impact could be slightly different. Additionally, the vulnerability allows an authenticated user to read, create, modify, and delete namespace properties in any namespace in any tenant. In Pulsar, namespace properties are reserved for user provided metadata about the namespace.

This issue affects Apache Pulsar versions from 2.7.1 to 2.10.6, from 2.11.0 to 2.11.4, from 3.0.0 to 3.0.3, from 3.1.0 to 3.1.3, and from 3.2.0 to 3.2.1.

3.0 Apache Pulsar users should upgrade to at least 3.0.4.
3.1 and 3.2 Apache Pulsar users should upgrade to at least 3.2.2.

Users operating versions prior to those listed above should upgrade to the aforementioned patched versions or newer versions.

Esta vulnerabilidad permite a los usuarios autenticados con permisos de producción o consumo realizar operaciones no autorizadas en temas particionados, como descargar temas y activar la compactación. Estas operaciones de administración deben restringirse a los usuarios con la función de administrador de inquilinos o la función de superusuario. Un usuario autenticado con permiso de producción puede crear suscripciones y actualizar propiedades de suscripción en temas particionados, aunque esto debería limitarse a usuarios con permisos de consumo. Este análisis de impacto supone que Pulsar se ha configurado con el proveedor de autorización predeterminado. Para los proveedores de autorizaciones personalizadas, el impacto podría ser ligeramente diferente. Además, la vulnerabilidad permite a un usuario autenticado leer, crear, modificar y eliminar propiedades de espacio de nombres en cualquier espacio de nombres de cualquier inquilino. En Pulsar, las propiedades del espacio de nombres están reservadas para los metadatos proporcionados por el usuario sobre el espacio de nombres. Este problema afecta a las versiones de Apache Pulsar de 2.7.1 a 2.10.6, de 2.11.0 a 2.11.4, de 3.0.0 a 3.0.3, de 3.1.0 a 3.1.3 y de 3.2.0 a 3.2. 1. Los usuarios de Apache Pulsar 3.0 deben actualizar al menos a 3.0.4. Los usuarios de Apache Pulsar 3.1 y 3.2 deben actualizar al menos a 3.2.2. Los usuarios que utilicen versiones anteriores a las enumeradas anteriormente deben actualizar a las versiones parcheadas antes mencionadas o a versiones más nuevas.
