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:

Host: target-ip:8807
Authorization: Bearer <YOUR_TOKEN>
Content-Type: application/x-www-form-urlencoded

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/donknap/dpanel, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update github.com/donknap/dpanel to 1.9.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-66292 is resolved across your whole dependency graph.

  3. Workarounds

    Resolve every user-supplied path to its canonical form and reject anything that escapes the intended directory, and run the component under an account that has no read or write access outside the directory it legitimately serves.
