介绍

# WordPress CVE-2024-10924 Exploit

📌 Overview

This repository contains a Proof-of-Concept (PoC) exploit for CVE-2024-10924, a vulnerability in the Really Simple SSL WordPress plugin that allows bypassing two-factor authentication (2FA). Attackers can exploit this flaw to log in as any user with a valid ID.

🚨 WARNING: This exploit is for educational and research purposes only. Unauthorized use against systems you do not own is illegal.


🚀 Exploit Usage

Prerequisites:
 - Python 3.x installed
 - Target WordPress site using the vulnerable version of "Really Simple SSL"

Installation:
  Clone the repository: |
    $ git clone https://github.com/h8sU/wordpress-cve-2024-10924-exploit.git
    $ cd wordpress-cve-2024-10924-exploit

Run the Exploit:
    $ python exploit.py <target_url> <user_id>

Example:
    $ python exploit.py http://web.com 1
    
This sends a crafted request to bypass 2FA authentication for the specified user_id.


🛡️ Mitigation & Fixes

How to Secure Your WordPress Site:
  - Update the Plugin - Ensure that "Really Simple SSL" is updated to the latest version where the vulnerability is patched.
  - Restrict REST API Access - Use security plugins like Wordfence to limit unauthorized API access.
  - Validate Nonces Properly - Ensure nonces are required and validated server-side before executing critical actions.
  - Use Strong Authentication Mechanisms - Implement additional security layers like Web Application Firewalls (WAF).
  - Monitor Access Logs - Check your logs for suspicious API requests to rest_route=/reallysimplessl/v1/two_fa/skip_onboarding.
  - Apply Code Fix - Ensure that the skip_onboarding function properly checks user authentication and nonce validation. The following code snippet demonstrates a recommended fix:

      try {
        $this->check_login_and_get_user($parameters->user_id, $parameters->login_nonce);
      } catch (Exception $e) {
        return new WP_REST_Response(['error' => $e->getMessage()], 403);
      }

    By implementing this fix, unauthorized requests will be denied with a 403 Forbidden response.
