Password Policy Bypass Vulnerability in Fides Webserver User Accept Invite API

CVE-2024-52008 → View on GitHub ↗ View on CVE.org ↗ View on NVD ↗

Description

Summary

The user invite acceptance API endpoint lacks server-side password policy enforcement, allowing users to set arbitrarily weak passwords by bypassing client-side validation. While the UI enforces password complexity requirements, direct API calls can circumvent these checks, enabling the creation of accounts with passwords as short as a single character.

Details

When an email messaging provider is enabled and a new user account is created in the system, an invite email containing a special link is sent to the new user's email address. This link directs the new user to a page where they can set their initial password. While the user interface implements password complexity checks, these validations are only performed client-side. The underlying /api/v1/user/accept-invite API endpoint does not implement the same password policy validations.

Impact

This vulnerability allows an invited user to set an extremely weak password for their own account during the initial account setup process. Therefore that specific user's account can be compromised easily by an attacker guessing or brute forcing the password.

Patches

The vulnerability has been patched in Fides version 2.50.0. Users are advised to upgrade to this version or later to secure their systems against this threat.

Workarounds

There are no workarounds.

Severity

This vulnerability has been assigned a severity of LOW.

Using CVSS v3.1 it could be scored as CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:N/A:N (5.7 Medium/Moderate), but the likelihood of a user bypassing client-side password complexity rules to set their own password is very low.

5.7 3.1 —
CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:N/A:N Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
Availability (A:N)
Service keeps running; no real outage angle.
