CVE-2024-52008: Password Policy Bypass Vulnerability in Fides Webserver
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.
