Description Jan Lieskovsky 2012-09-17 12:53:08 UTC 
A security flaw was found in the way Moodle course management system performed user permissions validation by course topic management. A remote attackers, with course editing capabilities, but without ability to show / hide topics or set the current topic for a particular course could use this flaw to successfully complete these actions under certain circumstances.
