Descriptions

CubeFS is an open-source cloud-native file storage system. A vulnerability was found in CubeFS prior to version 3.3.1 that could allow users to read sensitive data from the logs which could allow them escalate privileges. CubeFS leaks configuration keys in plaintext format in the logs. These keys could allow anyone to carry out operations on blobs that they otherwise do not have permissions for. For example, an attacker that has succesfully retrieved a secret key from the logs can delete blogs from the blob store. The attacker can either be an internal user with limited privileges to read the log, or they can be an external user who has escalated privileges sufficiently to access the logs. The vulnerability has been patched in v3.3.1. There is no other mitigation than upgrading.

CubeFS es un sistema de almacenamiento de archivos nativo de la nube de código abierto. Se encontró una vulnerabilidad en CubeFS anterior a la versión 3.3.1 que podría permitir a los usuarios leer datos confidenciales de los registros, lo que podría permitirles escalar privilegios. CubeFS filtra claves de configuración en formato de texto plano en los registros. Estas claves podrían permitir que cualquiera realice operaciones en blobs para las que de otro modo no tendría permisos. Por ejemplo, un atacante que haya recuperado con éxito una clave secreta de los registros puede eliminar blogs del almacén de blobs. El atacante puede ser un usuario interno con privilegios limitados para leer el registro o puede ser un usuario externo con privilegios aumentados lo suficiente para acceder a los registros. La vulnerabilidad ha sido parcheada en v3.3.1. No hay otra mitigación que la actualización.
