ethyca-fides Webserver API Path Traversal vulnerability

High severity GitHub Reviewed Published Jul 5, 2023 in ethyca/fides • Updated Nov 7, 2023

Package

pip ethyca-fides (pip)

Affected versions

< 2.15.1

Patched versions

2.15.1

Description

Impact

A path traversal (directory traversal) vulnerability affects fides versions lower than 2.15.1, allowing remote attackers to access arbitrary files on the fides webserver container's filesystem.

Patches

The vulnerability is patched in fides 2.15.1. Users should upgrade to this version.

Workarounds

If the Fides webserver API is not directly accessible to attackers and is instead deployed behind a reverse proxy as recommended in Ethyca's security best practice documentation, and the reverse proxy is an AWS application load balancer, the vulnerability can't be exploited by these attackers. An AWS application load balancer will reject this attack with a 400 error.

Additionally, any secrets supplied to the container using environment variables rather than a fides.toml configuration file are not affected by this vulnerability.

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.
