Motors Theme for WordPress | Up to and including 5.6.67
How the Exploit Works
The vulnerability stems from the Motors theme’s failure to validate a user’s identity properly before allowing password updates. This oversight allows unauthenticated attackers to change the passwords of arbitrary users, including administrators. Once the password is changed, the attacker can easily gain access to the user’s account, escalating their privileges and potentially compromising the system or leaking data.
Conceptual Example Code
Given the nature of this vulnerability, an attacker might exploit it using a simple POST request to the password update endpoint. This could look something like the following:
POST /wp-admin/user-edit.php HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
user_id=1&pass1=password&pass2=passwordIn this example, the attacker is attempting to change the password of the user with the ID of 1 (typically the admin user in WordPress installations) to “password”. As the Motors theme does not properly validate the identity of the user making this request, it accepts the new password and updates the user’s account accordingly.
Mitigation
The best way to mitigate this vulnerability is by applying a vendor-supplied patch. Users of the Motors theme should ensure that they are using version 5.6.68 or later, as these versions are not affected by CVE-2025-4322. If the patch cannot be applied immediately, users should consider employing a web application firewall (WAF) or intrusion detection system (IDS) to protect their systems in the interim.
