phpMyAdmin "setup.php" XSS Vulnerability

Omer Singer has reported a vulnerability in phpMyAdmin, which can be exploited by malicious people to conduct cross-site scripting attacks.

Input passed via the URL is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

Successful exploitation requires that the user is running a browser that has not URL-encoded the request (e.g. Internet Explorer 6).

The vulnerability is reported in version 2.11.1. Other versions may also be affected.
