Fides Server-Side Request Forgery Vulnerability in Custom Integration Upload

High severity GitHub Reviewed Published Oct 23, 2023 in ethyca/fides • Updated Nov 9, 2023

Package

pip ethyca-fides (pip)

Affected versions

< 2.22.1

Patched versions

2.22.1

Description

Impact

The Fides web application allows a custom integration to be uploaded as a ZIP file containing configuration and dataset definitions in YAML format.

It was discovered that specially crafted YAML dataset and config files allow a malicious user to perform arbitrary requests to internal systems and exfiltrate data outside the environment (also known as a Server-Side Request Forgery). The application does not perform proper validation to block attempts to connect to internal (including localhost) resources.

Exploitation is limited to API clients with the CONNECTOR_TEMPLATE_REGISTER authorization scope. In the Fides Admin UI this scope is restricted to highly privileged users, specifically root users and users with the owner role.

Patches

The vulnerability has been patched in Fides version 2.22.1. Users are advised to upgrade to this version or later to secure their systems against this threat.

Workarounds

There are no workarounds.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
