Description

### Summary DPanel has an arbitrary file deletion vulnerability in the `/api/common/attach/delete` interface. Authenticated users can delete arbitrary files on the server via path traversal. ### Details When a user logs into the administrative backend, this interface can be used to delete files. The vulnerability lies in the `Delete` function within the `app/common/http/controller/attach.go` file. The `path` parameter submitted by the user is directly passed to `storage.Local{}.GetSaveRealPath` and subsequently to `os.Remove` without proper sanitization or checking for path traversal characters (`../`).

Log in to the DPanel dashboard to obtain the `Authorization` token. 2. Send a POST request to delete a file (e.g., `/tmp/1.txt` inside the container). **Request:** ```http POST /dpanel/api/common/attach/delete HTTP/1.1 Host: target-ip:8807 Authorization: Bearer <YOUR_TOKEN> Content-Type: application/x-www-form-urlencoded path=../../../../../../../../tmp/1.txt ``` <img width="1600" height="940" alt="image" src="https://github.com/user-attachments/assets/40e4d3cb-57f7-4a4e-adcc-a9503af762be" /> <img width="346" height="191" alt="image" src="https://github.com/user-attachments/assets/756c0891-e61b-434c-9386-6e701bbb1a97" /> <img width="1310" height="885" alt="image" src="https://github.com/user-attachments/assets/31c883c2-725e-4618-977c-35fe19adafb1" /> <img width="1009" height="209" alt="image" src="https://github.com/user-attachments/assets/2641fdfb-6d73-4940-bd92-44d748e0e6b7" /> <img width="1265" height="876" alt="image" src="https://github.com/user-attachments/assets/14c67ec8-ec37-4820-90be-a24f58819020" />
