Vulnerability from github – Published: 2022-10-25 20:21 – Updated: 2023-06-27 21:55
VLAI
Summary
OpenFGA Authorization Bypass via tupleset wildcard
Details

Overview

During our internal security assessment, it was discovered that OpenFGA versions v0.2.3 and prior are vulnerable to authorization bypass under certain conditions.

Am I affected?

You are affected by this vulnerability if you are using openfga/openfga version v0.2.3 and you added a tuple with a wildcard (*) assigned to a tupleset relation (the right hand side of a ‘from’ statement).

How to fix that?

Upgrade to version v0.2.4.

Backward Compatibility

This update is not backward compatible with any authorization model that uses wildcard on a tupleset relation.

Mitigation
Architecture and Design
  • Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) [REF-229] to enforce the roles at the appropriate boundaries.
  • Note that this approach may not protect against horizontal authorization, i.e., it will not protect a user from attacking others with the same role.
Mitigation
Architecture and Design

Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records. For example, a database may restrict access for medical records to a specific database user, but each record might only be intended to be accessible to the patient and the patient's doctor [REF-7].

Mitigation MIT-4.4
Architecture and Design

Strategy: Libraries or Frameworks

  • Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
  • For example, consider using authorization frameworks such as the JAAS Authorization Framework [REF-233] and the OWASP ESAPI Access Control feature [REF-45].
Mitigation
Architecture and Design
  • For web applications, make sure that the access control mechanism is enforced correctly at the server side on every page. Users should not be able to access any unauthorized functionality or information by simply requesting direct access to that page.
  • One way to do this is to ensure that all pages containing sensitive information are not cached, and that all such pages restrict access to requests that are accompanied by an active and authenticated session token associated with a user who has the required permissions to access that page.
Mitigation
System Configuration Installation

Use the access control capabilities of your operating system and server environment and define your access control lists accordingly. Use a "default deny" policy when defining these ACLs.
