| tiêu đề | GitHub hsweb-framework 5.0.0 Path Traversal: '../filedir' |
|---|
| Mô tả | The file upload function of hsweb-framework contains a path traversal vulnerability. Attackers could exploit this vulnerability to overwrite important files on the server (depending on the type of application running the framework). For example, overwriting a JAR file could pollute the classpath, leading to arbitrary code execution, or it could overwrite SSH or scheduled tasks.
Prepare a file to be overwritten locally. Add the file type to the hsweb configuration and specify `useOriginalFileName`. Then, run the following command: `curl -X POST http://localhost:8080/file/static -F "file=@./pom.xml;filename=../../../../../../pom.xml"`.
The name variable is completely user-controllable. It can navigate to the parent directory via ../. The framework expects the upload directory to be /target/upload/20260126/2015638779023392768, but in reality, the payload will be uploaded to the root directory, resulting in arbitrary file writing. |
