[CVE-2014-3876] The parameter akey is reflected unfiltered as part of the HTML page. Some characters are forbidden in the GET parameter due to filtering of the URL, but this can be circumvented by using a POST parameter. Nevertheless, this issue is exploitable via the GET parameter alone, with some user interaction.
