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.
