CVE-2024-29834: Apache Pulsar: Improper Authorization For Namespace and Topic Management Endpoints

[Lari Hotari <lhotari () apache org>]

Affected versions:

- Apache Pulsar 2.7.1 through 2.10.6
- Apache Pulsar 2.11.0 through 2.11.4
- Apache Pulsar 3.0.0 before 3.0.4
- Apache Pulsar 3.1.0 through 3.1.3
- Apache Pulsar 3.2.0 before 3.2.2

Description:

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.
