CVE-2026-6418

Full vulnerability record from the local CVENow database.

Description

An issue was discovered in the Shared Account Synchronization component of PaperCut MF (version 25.0.4). The application allows administrative users to configure a source path for account data synchronization. Due to a lack of proper path validation and sanitization, an authenticated user with administrative privileges can specify arbitrary file paths on the local file system. This allows for the enumeration of directory structures and the unauthorized reading of sensitive text-based configuration or system files. When the synchronization process is triggered, the application attempts to parse the contents of the specified file, subsequently exposing the data within the application's account management interface. This vulnerability could lead to the disclosure of sensitive system information or configuration details, depending on the permissions of the service account under which the application is running.

      "value": "Se descubrió un problema en el componente de Sincronización de Cuentas Compartidas de PaperCut MF (versión 25.0.4). La aplicación permite a los usuarios administrativos configurar una ruta de origen para la sincronización de datos de cuentas.\n\nDebido a una falta de validación y saneamiento de rutas adecuados, un usuario autenticado con privilegios administrativos puede especificar rutas de archivo arbitrarias en el sistema de archivos local. Esto permite la enumeración de estructuras de directorio y la lectura no autorizada de archivos de configuración o de sistema sensibles basados en texto.\n\nCuando se activa el proceso de sincronización, la aplicación intenta analizar el contenido del archivo especificado, exponiendo posteriormente los datos dentro de la interfaz de gestión de cuentas de la aplicación. Esta vulnerabilidad podría conducir a la divulgación de información sensible del sistema o detalles de configuración, dependiendo de los permisos de la cuenta de servicio bajo la cual se está ejecutando la aplicación."
