Component: Core

Improper access control in Odoo Community 15.0 and earlier and Odoo
Enterprise 15.0 and earlier allows remote authenticated users to trigger
the creation of demonstration data, including user accounts with known
credentials.

I. Background

To be able to quickly demonstrate features, demonstration data can be added to
an existing Odoo instance. This creates fake employees, products and other
demonstration data.

II. Problem Description

This feature could be triggered by any user instead of only administrators.

III. Impact

Attack Vector: Network exploitable
Authentication: Employee / Portal user account required
CVSS3 Score: High :: 7.1
CVSS3 Vector: CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N

A malicious low priviledge user (including portal user accounts) on an Odoo
database might install demonstration data and use this as a way to gain
access to restricted data or features.

Odoo S.A. is not aware of any use of this vulnerability in the wild but any case
would result on a new user “demo” being created.

IV. Workaround

No workaround is available, updating to the latest revision or applying the
corresponding patch is strongly recommended.

Odoo Cloud servers have been patched as soon as the correction was available.

V. Solution

Update to the latest revision, either via GitHub or by downloading it:
