Authentication Bypass Using an Alternate Path or Channel

CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

CVE	CVE-2024-10924
CVSS	9.8 (Critical)
Publicly Published	November 14, 2024
Last Updated	November 15, 2024
Researcher	István Márton - Wordfence

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).
