Input passed to the 'RequestName' header parameter when posting to
'/ajax/updatecheck.php' is not sanitized before it is 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.
Example:
http://somehost/ajax/updatecheck.php?PostBackKey=1&ExtensionKey=1&RequestName=1<script>alert(123)</script>
will return:
1<script>alert(123)</script>|[ERROR]There was a problem authenticating your
post information.
