Streszczenie

W Apache Pulsar endpoint functions connectors (/admin/v2/functions/connectors i /admin/v3/functions/connectors) zwraca katalog connectorów IO bez wymagania uprawnień super-użytkownika, podczas gdy endpoint worker connectors wymaga takich uprawnień. W rezultacie każdy uwierzytelniony klient może odczytać metadane katalogu connectorów niezależnie od posiadanej roli. Luka dotyczy wersji od 2.4.1 do 4.0.13 oraz od 4.1.0 do 4.2.4.

Ocena ryzyka

Ujawnienie metadanych katalogu connectorów (nazwy, opisy, nazwy klas) może ułatwić rozpoznanie środowiska, w tym ujawnić nazwy niestandardowych connectorów zainstalowanych przez operatora. Luka nie pozwala na modyfikację katalogu ani zarządzanie connectorami.

Rekomendacja

Zaktualizuj Apache Pulsar do wersji co najmniej 4.0.14 (dla linii 4.0.x) lub 4.2.5 (dla linii 4.1.x i 4.2.x). Klienci bez uprawnień super-użytkownika mogą używać wbudowanych endpointów sources i sinks do listowania dostępnych typów connectorów.

Oryginalny opis (angielski, źródło NVD)

The Pulsar Functions worker REST API provides two endpoints that return the catalog of Pulsar IO connectors installed on the functions worker: the worker connectors endpoint (/admin/v2/worker/connectors) and the deprecated functions connectors endpoint (/admin/v2/functions/connectors and /admin/v3/functions/connectors). When authorization is enabled, the worker connectors endpoint requires super-user access. The functions connectors endpoint, served both by the functions worker and by a broker running the functions worker, returns the same catalog without this check. As a result, when authentication and authorization are enabled, any authenticated client can read the connector catalog through the functions connectors endpoint, regardless of the permissions granted to its role and without super-user access. Unauthenticated requests are rejected unless anonymous access is configured with an anonymous user role. The catalog contains the connector type definitions installed in the functions worker's connectors directory: the connector name, its description, and the source, sink and configuration class names. It does not contain configured source or sink instances, their configuration values or credentials, and an installed connector type does not indicate that a connector is configured or running. The impact is limited to disclosure of this metadata, which can include the names and descriptions of custom connectors installed by the operator. The issue does not allow modifying the catalog or managing connectors. Connector definitions that have a source or sink class are also returned by the built-in sources and sinks endpoints to authenticated clients. In fixed versions, the functions connectors endpoint applies the same checks as the worker connectors endpoint, so that it requires super-user access when authorization is enabled. Clients that are not super-users can use the built-in sources and sinks endpoints to list the available connector types. This issue affects Apache Pulsar versions from 2.4.1 before 4.0.14 and from 4.1.0 before 4.2.5. - 4.0.x version users should upgrade to at least 4.0.14. - 4.1.x and 4.2.x version users should upgrade to at least 4.2.5. Users operating versions prior to those listed above should upgrade to the aforementioned patched versions or newer versions. The currently supported Apache Pulsar release lines are 4.0.x and 5.0.x. The supported versions schedule is available at https://pulsar.apache.org/contribute/release-policy/.
