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.\n\nThis 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.\n\nThe 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.\n\n2.10 Pulsar Proxy users should upgrade to at least 2.10.6.\n2.11 Pulsar Proxy users should upgrade to at least 2.11.3.\n3.0 Pulsar Proxy users should upgrade to at least 3.0.2.\n3.1 Pulsar Proxy users should upgrade to at least 3.1.1.\n\nUsers 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."}, {"lang": "es", "value": "Una vulnerabilidad de autenticaci\u00f3n incorrecta en Apache Pulsar Proxy permite a un atacante conectarse al endpoint /proxy-stats sin autenticaci\u00f3n. El endpoint vulnerable expone estad\u00edsticas detalladas sobre conexiones activas, junto con la capacidad de modificar el nivel de registro de conexiones proxy sin requerir credenciales de autenticaci\u00f3n adecuadas. Este problema afecta a las versiones de Apache Pulsar de 2.6.0 a 2.10.5, de 2.11.0 a 2.11.2, de 3.0.0 a 3.0.1 y 3.1.0. Los riesgos conocidos incluyen la exposici\u00f3n de informaci\u00f3n confidencial, como la IP del cliente conectado, y la manipulaci\u00f3n no autorizada del nivel de registro, lo que podr\u00eda conducir a una condici\u00f3n de denegaci\u00f3n de servicio al aumentar significativamente la sobrecarga de registro del proxy. Cuando se implementa a trav\u00e9s del gr\u00e1fico Apache Pulsar Helm dentro de entornos de Kubernetes, es posible que la IP real del cliente no se revele a trav\u00e9s del comportamiento predeterminado del balanceador de carga, que normalmente oscurece las direcciones IP de origen originales cuando externalTrafficPolicy se configura en \"Cl\u00faster\" de forma predeterminada. El endpoint /proxy-stats contiene estad\u00edsticas a nivel de tema; sin embargo, en la configuraci\u00f3n predeterminada, no se sabe que las estad\u00edsticas a nivel de tema est\u00e9n expuestas. 2.10 Los usuarios de Pulsar Proxy deben actualizar al menos a 2.10.6. 2.11 Los usuarios de Pulsar Proxy deben actualizar al menos a 2.11.3.
