At a glance

CVE-2024-10245 is a critical-severity Authentication Bypass Using an Alternate Path or Channel vulnerability in the Relais 2FA WordPress plugin, affecting versions <= 1.0. It carries a CVSS score of 9.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. No fixed release has been reported yet; treat installations running this software as exposed. Disclosed November 2024, reported by István Márton.

Vulnerability Overview

The Relais 2FA plugin for WordPress is vulnerable to authentication bypass in versions up to, and including, 1.0. This is due to incorrect authentication and capability checking in the 'rl_do_ajax' function. This makes it possible for unauthenticated attackers to log in as any existing user on the site, such as an administrator, if they have access to the email.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-288: Authentication Bypass Using an Alternate Path or Channel

Relais 2FA <= 1.0 carries this weakness at rl_do_ajax, and reaching it takes a caller who can reach the endpoint. Authentication bypass through an alternate path means the application has a second route to a protected action that skips the checks the primary route performs.

The protection on the main path becomes irrelevant, because the attacker simply uses the route that never asks. No fixed build of this plugin is recorded for Relais 2FA yet, so installs running <= 1.0 stay exposed until the vendor ships one.

Remediation

No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.

How does WordSec protect against this?

Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
