Vulnerability Breakdown

As mentioned earlier, this vulnerability exists due to inadequate CSRF protection, specifically concerning the feature allowing a user to migrate rule types within the plugin settings page. This weak CSRF protection allows an attacker to craft and execute malicious requests, potentially leading to unauthorized rule type migration, severely compromising the security and functionality of a website.

Here's a code snippet showcasing the absence of proper CSRF protection in the affected plugin versions:

function migrate_to_combined_simple() {
    global $wpdb;
    $rules_table = $wpdb->prefix . 'adp_rules';

    if (isset($_POST['migrate_to_version'])) {
        $version = $_POST['migrate_to_version'];

        if ($version === '153') {
            // ... Migration code goes here ...
            echo 1; // return success
        } else {
            echo ; // return failure
        }
        exit();
    }
}

As you can see, the code lacks the necessary nonce checks and CSRF token implementation to ensure that only legitimate requests are processed. This lack of security measures leaves the function vulnerable to CSRF attacks initiated by a malicious user.
