Vulnerability details

ChurchCRM is an open-source church management system. In versions prior to 7.2.0, the /api/public/user/login endpoint validates only the username and password before returning the user's API key, bypassing the normal authentication flow that enforces account lockout and two-factor authentication checks.…

more

An attacker with knowledge of a user's password can obtain API access even when the account is locked or has 2FA enabled, granting direct access to all protected API endpoints with that user's privileges. This issue has been fixed in version 7.2.0. Note: this issue had a duplicate, GHSA-472m-p3gf-46xp, which has been closed.

Why these techniques?

Auth bypass on public /api/public/user/login endpoint allows valid creds to skip 2FA/lockout for direct API access (T1190 + T1078).

Mitigating Controls

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

AC-17 Remote Access
addresses: CWE-288

Authorizing remote access reduces the ability to bypass authentication via unauthorized alternate remote channels.

AC-9 Previous Logon Notification
addresses: CWE-288

Users can identify logons via alternate paths or channels by reviewing the previous logon time.

IA-10 Adaptive Authentication
addresses: CWE-288

Adaptive requirements can apply across access paths, reducing the ability to bypass authentication via alternate channels or paths.

IA-13 Identity Providers and Authorization Servers
addresses: CWE-288

Centralized IdPs close alternate authentication paths that enable bypass.

IA-8 Identification and Authentication (Non-organizational Users)
addresses: CWE-288

Enforces authentication for non-organizational users, making it harder to bypass via alternate paths or channels.

SC-11 Trusted Path
addresses: CWE-288

Requires authentication to occur exclusively over the isolated trusted path, directly preventing bypass via alternate or untrusted channels.
