| 标题 | lsFusion 6.1 Arbitrary File Upload |
|---|
| 描述 | Accessing the /uploadFile API invokes the handleRequest method in UploadFileRequestHandler. This method accepts an unvalidated sid parameter, which is directly appended to FileUtils.APP_UPLOAD_FOLDER_PATH. Additionally, there are no restrictions on the uploaded filename. When combined with directory traversal, this allows an attacker to upload JSP files to a web-accessible directory, leading to client-side file upload–based remote code execution (RCE). |
