source: http://www.securityfocus.com/bid/28455/info Blackboard Academic Suite is prone to multiple cross-site scripting vulnerabilities because the application fails to properly sanitize user-supplied input. An attacker may leverage these issues to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may help the attacker steal cookie-based authentication credentials and launch other attacks. Blackboard versions prior to 184.108.40.2063, 7.0.404.58, 7.1.467.35, 7.2.383.45, and 220.127.116.11 are vulnerable. http://www.example.com/bin/common/announcement.pl?action=ADD&course_id=_137839_1&render_type=EDITABLE&context=course<input type="text" name="data__announcements___pk1_pk2__subject"value=?<script>alert(?worm activated!?)</script>? />
