Moodle — система управления образовательными электронными курсами

mod/data/preset.php in Moodle 2.1.x before 2.1.6 and 2.2.x before 2.2.3 does not properly iterate through an array, which allows remote authenticated users to overwrite arbitrary database activity presets via unspecified vectors.

The Multi-Authentication feature in the Central Authentication Service (CAS) functionality in auth/cas/cas_form.html in Moodle 2.1.x before 2.1.6 and 2.2.x before 2.2.3 does not use HTTPS, which allows remote attackers to obtain credentials by sniffing the network.

Moodle 2.0.x before 2.0.9, 2.1.x before 2.1.6, and 2.2.x before 2.2.3 allows remote authenticated users to bypass an activity's read-only state and modify the database by leveraging the student role and editing database activity entries that already exist.
