Security Advisory - CVE-2021-23166

Affects: Odoo 15.0 and earlier (Community and Enterprise Editions)
CVE ID: CVE-2021-23166
Component: Core

A sandboxing issue in Odoo Community 15.0 and earlier and Odoo Enterprise
15.0 and earlier allows authenticated administrators to read and write
local files on the server.

I. Background

Odoo uses the Python library psycopg2 to interact with the PostgreSQL database.

II. Problem Description

The pyscopg2 library could be abused to access the local files of the server
running the Odoo instance.

III. Impact

Attack Vector: Network exploitable
Authentication: Privileged user account required
CVSS3 Score: high :: 8.7
CVSS3 Vector: CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:N

A malicious administrator might be able to read or modify sensitive files stored
on the server such as protected configuration secrets.

Systems who host Odoo databases for untrusted users are particularly at risk,
(e.g. SaaS platforms), as they typically allow users to become administrators
of their own Odoo database. This is sufficient to exploit the vulnerability.

Odoo S.A. is not aware of any use of this vulnerability in the wild.

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:
