pfSense contains a flaw that allows a remote cross-site scripting (XSS) attack. This flaw exists because the application does not validate the 'pkg' parameter upon submission to the /usr/local/www/pkg_mgr_install.php script. This may allow an attacker to create a specially crafted request that would execute arbitrary script code in a user's browser within the trust relationship between their browser and the server.
