Description Laura Pardo 2018-09-17 16:05:12 UTC

A flaw was found in Moodle. When importing legacy 'drag and drop into text' (ddwtos) type quiz questions, it was possible to inject and execute PHP code from within the imported questions, either intentionally or by importing questions from an untrusted source.
