CVSS: 8.5EPSS: 0%CPEs: 5EXPL: 0CVE-2024-27894 – Apache Pulsar: Pulsar Functions Worker Allows Unauthorized File Access and Unauthorized HTTP/HTTPS Proxying
https://notcve.org/view.php?id=CVE-2024-27894
The Pulsar Functions Worker includes a capability that permits authenticated users to create functions where the function's implementation is referenced by a URL. The supported URL schemes include "file", "http", and "https". When a function is created using this method, the Functions Worker will retrieve the implementation from the URL provided by the user. However, this feature introduces a vulnerability that can be exploited by an attacker to gain unauthorized access to any file that the Pulsar Functions Worker process has permissions to read. This includes reading the process environment which potentially includes sensitive information, such as secrets. • http://www.openwall.com/lists/oss-security/2024/03/12/11 https://lists.apache.org/thread/45cqhgqg8d19ongjw18ypcss8vwh206p https://pulsar.apache.org/security/CVE-2024-27894 • CWE-20: Improper Input Validation CWE-552: Files or Directories Accessible to External Parties •
CVSS: 8.4EPSS: 0%CPEs: 5EXPL: 0CVE-2024-27317 – Apache Pulsar: Pulsar Functions Worker's Archive Extraction Vulnerability Allows Unauthorized File Modification
https://notcve.org/view.php?id=CVE-2024-27317
In Pulsar Functions Worker, authenticated users can upload functions in jar or nar files. These files, essentially zip files, are extracted by the Functions Worker. However, if a malicious file is uploaded, it could exploit a directory traversal vulnerability. This occurs when the filenames in the zip files, which aren't properly validated, contain special elements like ". • http://www.openwall.com/lists/oss-security/2024/03/12/10 https://lists.apache.org/thread/ct9xmvlf7lompc1pxvlsb60qstfsm9po https://pulsar.apache.org/security/CVE-2024-27317 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
CVSS: 8.5EPSS: 0%CPEs: 5EXPL: 0CVE-2024-27135 – Apache Pulsar: Improper Input Validation in Pulsar Function Worker allows Remote Code Execution
https://notcve.org/view.php?id=CVE-2024-27135
Improper input validation in the Pulsar Function Worker allows a malicious authenticated user to execute arbitrary Java code on the Pulsar Function worker, outside of the sandboxes designated for running user-provided functions. This vulnerability also applies to the Pulsar Broker when it is configured with "functionsWorkerEnabled=true". This issue affects Apache Pulsar versions from 2.4.0 to 2.10.5, from 2.11.0 to 2.11.3, from 3.0.0 to 3.0.2, from 3.1.0 to 3.1.2, and 3.2.0. 2.10 Pulsar Function Worker users should upgrade to at least 2.10.6. 2.11 Pulsar Function Worker users should upgrade to at least 2.11.4. 3.0 Pulsar Function Worker users should upgrade to at least 3.0.3. 3.1 Pulsar Function Worker users should upgrade to at least 3.1.3. 3.2 Pulsar Function Worker users should upgrade to at least 3.2.1. Users operating versions prior to those listed above should upgrade to the aforementioned patched versions or newer versions. La validación de entrada incorrecta en Pulsar Function Worker permite que un usuario autenticado malicioso ejecute código Java arbitrario en Pulsar Function Worker, fuera de los entornos limitados designados para ejecutar funciones proporcionadas por el usuario. Esta vulnerabilidad también se aplica al Pulsar Broker cuando está configurado con "functionsWorkerEnabled=true". Este problema afecta a las versiones de Apache Pulsar de 2.4.0 a 2.10.5, de 2.11.0 a 2.11.3, de 3.0.0 a 3.0.2, de 3.1.0 a 3.1.2 y 3.2.0. 2.10 Los usuarios de Pulsar Function Worker deben actualizar al menos a 2.10.6. 2.11 Los usuarios de Pulsar Function Worker deben actualizar al menos a 2.11.4. • http://www.openwall.com/lists/oss-security/2024/03/12/9 https://lists.apache.org/thread/dh8nj2vmb2br6thjltq74lk9jxkz62wn https://pulsar.apache.org/security/CVE-2024-27135 • CWE-20: Improper Input Validation CWE-913: Improper Control of Dynamically-Managed Code Resources •
CVSS: 8.2EPSS: 0%CPEs: 4EXPL: 0CVE-2022-34321 – Apache Pulsar: Improper Authentication for Pulsar Proxy Statistics Endpoint
https://notcve.org/view.php?id=CVE-2022-34321
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. • http://www.openwall.com/lists/oss-security/2024/03/12/8 https://lists.apache.org/thread/ods5tq2hpl390hvjnvxv0bcg4rfpgjj8 https://pulsar.apache.org/security/CVE-2022-34321 • CWE-306: Missing Authentication for Critical Function •

https://notcve.org/view.php?id=CVE-2024-28098
The vulnerability allows authenticated users with only produce or consume permissions to modify topic-level policies, such as retention, TTL, and offloading settings. These management operations should be restricted to users with the tenant admin role or super user role. This issue affects Apache Pulsar versions from 2.7.1 to 2.10.5, from 2.11.0 to 2.11.3, from 3.0.0 to 3.0.2, from 3.1.0 to 3.1.2, and 3.2.0. 2.10 Apache Pulsar users should upgrade to at least 2.10.6. 2.11 Apache Pulsar users should upgrade to at least 2.11.4. 3.0 Apache Pulsar users should upgrade to at least 3.0.3. 3.1 Apache Pulsar users should upgrade to at least 3.1.3. 3.2 Apache Pulsar users should upgrade to at least 3.2.1. Users operating versions prior to those listed above should upgrade to the aforementioned patched versions or newer versions. La vulnerabilidad permite a los usuarios autenticados con permisos solo de producción o consumo modificar políticas a nivel de tema, como retención, TTL y configuraciones de descarga. Estas operaciones de administración deben restringirse a usuarios con la función de administrador de inquilinos o la función de superusuario.
