SCA: security update for org.apache.pulsar:pulsar-proxy (GHSA-c35h-w8hj-mm55)

high Tenable Self-Hosted Container Security Plugin ID 413606

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- Improper Authentication vulnerability in Apache Pulsar Proxy allows an attacker to connect to the /proxy-
stats endpoint without authentication. The vulnerable endpoint exposes detailed statistics about live
connections, along with the capability to modify the logging level of proxied connections without
requiring proper authentication credentials. This issue affects Apache Pulsar versions from 2.6.0 to
2.10.5, from 2.11.0 to 2.11.2, from 3.0.0 to 3.0.1, and 3.1.0. The known risks include exposing sensitive
information such as connected client IP and unauthorized logging level manipulation which could lead to a
denial-of-service condition by significantly increasing the proxy's logging overhead. When deployed via
the Apache Pulsar Helm chart within Kubernetes environments, the actual client IP might not be revealed
through the load balancer's default behavior, which typically obscures the original source IP addresses
when externalTrafficPolicy is being configured to "Cluster" by default. The /proxy-stats endpoint contains
topic level statistics, however, in the default configuration, the topic level statistics aren't known to
be exposed. 2.10 Pulsar Proxy users should upgrade to at least 2.10.6. 2.11 Pulsar Proxy users should
upgrade to at least 2.11.3. 3.0 Pulsar Proxy users should upgrade to at least 3.0.2. 3.1 Pulsar Proxy
users should upgrade to at least 3.1.1. Users operating versions prior to those listed above should
upgrade to the aforementioned patched versions or newer versions. Additionally, it's imperative to
recognize that the Apache Pulsar Proxy is not intended for direct exposure to the internet. The
architectural design of Pulsar Proxy assumes that it will operate within a secured network environment,
safeguarded by appropriate perimeter defenses. (CVE-2022-34321)
