Descriptions
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 "..", altering the directory path. This could allow an attacker to create or modify files outside of the designated extraction directory, potentially influencing system behavior. 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.
En Pulsar Functions Worker, los usuarios autenticados pueden cargar funciones en archivos jar o nar. Estos archivos, esencialmente archivos zip, son extraídos por Functions Worker. Sin embargo, si se carga un archivo malicioso, podría aprovechar una vulnerabilidad de cruce de directorio. Esto ocurre cuando los nombres de los archivos zip, que no están validados correctamente, contienen elementos especiales como "..", alterando la ruta del directorio. Esto podría permitir a un atacante crear o modificar archivos fuera del directorio de extracción designado, lo que podría influir en el comportamiento del sistema. 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. Los usuarios de 3.0 Pulsar Function Worker deben actualizar al menos a 3.0.3. 3.1 Los usuarios de Pulsar Function Worker deben actualizar al menos a 3.1.3. 3.2 Los usuarios de Pulsar Function Worker deben actualizar al menos a 3.2.1. Los usuarios que utilicen versiones anteriores a las enumeradas anteriormente deben actualizar a las versiones parcheadas antes mencionadas o a versiones más nuevas.
