Hotaru CMS is an open source, PHP platform for building your own websites. With flexible plugins and themes, you can make any site you like.
The CMS suffers from multiple XSS vulnerabilities. Input thru the POST parameters 'SITE_NAME' (stored), 'return' (reflected) and the GET parameter 'search' (reflected) thru Hotaru.php, are not sanitized allowing the attacker to execute HTML code into user's browser session on the affected site.
