- Advisory ID: DRUPAL-SA-CONTRIB-2016-047
- Project: Panels (third-party module)
- Version: 7.x
- Date: 2016-August-17
- Security risk: 15/25 ( Critical) AC:None/A:None/CI:All/II:None/E:Theoretical/TD:All
- Vulnerability: Access bypass, Information Disclosure
Description
Panels does not check access on some routes (Critical)
Panels allows users with certain permissions to modify the layout and panel panes on pages or entities utilizing panels.
Much of the functionality to modify these panels rely on backend routes that call administrative forms. These forms did not provide any access checks, or site specific encoded urls. This can allow an attacker to guess the backend url as an anonymous user and see data loaded for the form.
There is no mitigation for this exploit. Any site with panels enabled is vulnerable.
Panels In-place Editor does not properly check for access (Moderately Critical)
The Panels In-Place Editor (IPE) allows users with certain permissions to modify the layout and panel content of pages.
The default behavior for Panels IPE is to allow any user with the permissions “Use the Panels In-Place Editor” and “Change layouts with the Panels In-Place Editor ” access to the IPE regardless of whether or not a user has proper access to the page. While users cannot edit the page content itself, they can change the layout and the different panel panes shown.
This vulnerability is mitigated by the fact that an attacker must have a role with the permission “Use the Panels In-Place Editor” and the IPE must be enabled for the specific content type.
