Detailsinfo

A vulnerability classified as critical was found in Ethyca Fides up to 2.69.0. Affected by this vulnerability is some unknown processing of the component Fides Admin UI Login Endpoint. The manipulation with an unknown input leads to a excessive authentication vulnerability. The CWE definition for the vulnerability is CWE-307. The product does not implement sufficient measures to prevent multiple failed authentication attempts within a short time frame, making it more susceptible to brute force attacks. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Fides is an open-source privacy engineering platform. Prior to version 2.69.1, the Fides Admin UI login endpoint relies on a general IP-based rate limit for all API traffic and lacks specific anti-automation controls designed to protect against brute-force attacks. This could allow attackers to conduct credential testing attacks, such as credential stuffing or password spraying, which poses a risk to accounts with weak or previously compromised passwords. Version 2.69.1 fixes the issue. For organizations with commercial Fides Enterprise licenses, configuring Single Sign-On (SSO) through an OIDC provider (like Azure, Google, or Okta) is an effective workaround. When OIDC SSO is enabled, username/password authentication can be disabled entirely, which eliminates this attack vector. This functionality is not available for Fides Open Source users.
