Description Jan Lieskovsky 2012-09-17 14:23:57 UTC

A security flaw was found in the way Moodle course management system performed permission check on course reset page (the course reset link was protected by a correct permission, but the reset page itself was being checked for a different permission). A remote attacker could use this flaw to in an unauthorized way to reset particular course.
