Oneup · Oneup/Uploader-Bundle · CVE-2020-5237
**Name of the Vulnerable Software and Affected Versions** oneup/uploader-bundle versions 1.9.0 through 1.9.2 oneup/uploader-bundle versions 2.0.0 through 2.1.4 **Description** The issue allows remote attackers to upload, copy, and modify files on the filesystem, potentially leading to arbitrary code execution. This is achieved via various parameters in different controllers, such as the `filename` parameter to `BlueimpController.php`, the `dzchunkindex`, `dzuuid`, or `filename` parameter to `DropzoneController.php`, the `qqpartindex`, `qqfilename`, or `qquuid` parameter to `FineUploaderController.php`, the `x-file-id` or `x-file-name` parameter to `MooUploadController.php`, or the `name` or `chunk` parameter to `PluploadController.php`. The vulnerability can be exploited by any users with legitimate access to the upload functionality and can lead to arbitrary code execution, denial of service, and disclosure of confidential information. **Recommendations** For oneup/uploader-bundle versions 1.9.0 through 1.9.2, update to version 1.9.3. For oneup/uploader-bundle versions 2.0.0 through 2.1.4, update to version 2.1.5. As a temporary workaround, consider restricting access to the upload functionality until a patch is applied. Avoid using the vulnerable parameters, such as `filename`, `dzchunkindex`, `dzuuid`, `qqpartindex`, `qqfilename`, `qquuid`, `x-file-id`, `x-file-name`, `name`, and `chunk`, in the affected API endpoints until the issue is resolved.
