Description Vasyl Kaigorodov 2015-01-28 14:25:31 UTC

Upstream reports:

Parameter "file" passed to scripts serving JS was not always cleaned from including "../" in the path, allowing to read files located outside of moodle directory. All OS are affected but especially vulnerable are Windows servers
Reported by:       Emiel Florijn
