OpenFlashChart is a library used to render dashboards and reports in CiviCRM v3+. The library includes a program written for Adobe Flash which accepts data via query string. The data is not properly sanitisized. If an attacker provides an authorized user with a maliciously constructed link, the attacker can cause the user to execute arbitrary JavaScript code.
