CVE-2024-24771 Detail

Description

Open Forms allows users create and publish smart forms. Versions prior to 2.2.9, 2.3.7, 2.4.5, and 2.5.2 contain a non-exploitable multi-factor authentication weakness. Superusers who have their credentials (username + password) compromised could potentially have the second-factor authentication bypassed if an attacker somehow managed to authenticate to Open Forms. The maintainers of Open Forms do not believe it is or has been possible to perform this login. However, if this were possible, the victim's account may be abused to view (potentially sensitive) submission data or have been used to impersonate other staff accounts to view and/or modify data. Three mitigating factors to help prevent exploitation include: the usual login page (at `/admin/login/`) does not fully log in the user until the second factor was succesfully provided; the additional non-MFA protected login page at `/api/v2/api-authlogin/` was misconfigured and could not be used to log in; and there are no additional ways to log in. This also requires credentials of a superuser to be compromised to be exploitable. Versions 2.2.9, 2.3.7, 2.4.5, and 2.5.2 contain the following patches to address these weaknesses: Move and only enable the API auth endpoints (`/api/v2/api-auth/login/`) with `settings.DEBUG = True`. `settings.DEBUG = True` is insecure and should never be applied in production settings. Additionally, apply a custom permission check to the hijack flow to only allow second-factor-verified superusers to perform user hijacking.


Severity



CVSS 3.x Severity and Metrics:

NIST CVSS score
NIST: NVD
Base Score:  5.9 MEDIUM
Vector:  CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:N

Nist CVSS score does not match with CNA score
CNA:  GitHub, Inc.
Base Score:  7.7 HIGH
Vector:  CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:N


NVD Analysts use publicly available information to associate vector strings and CVSS scores. We also display any CVSS information provided within the CVE List from the CNA.

Note: It is possible that the NVD CVSS may not match that of the CNA. The most common reason for this is that publicly available information does not provide sufficient detail or that information simply was not available at the time the CVSS vector string was assigned.
