There is a reflected XSS vulnerability in the following php code ./tera-charts/charts/treemap.php: 52: var data_filename = "<?php echo $_GET['fn']; ?>"; 55: var chart_userid = "<?php echo $_GET['userid']; ?>"; The variable fn appears to send unsanitized data back to the users browser.
Exploit was derived from appearance of first vulnerable parameter in code, there could be more shown above.
