admin/uploaduser_form.php in Moodle 2.0.x before 2.0.3 does not force password changes for autosubscribed users, which makes it easier for remote attackers to obtain access by leveraging knowledge of the initial password of a new user.

Moodle 2.0.x before 2.0.3 allows remote authenticated users to cause a denial of service (invalid database records) via a series of crafted ratings operations.

Moodle 1.9.x before 1.9.12 and 2.0.x before 2.0.3 does not properly implement associations between teachers and groups, which allows remote authenticated users to read quiz reports of arbitrary students by leveraging the teacher role.

Multiple cross-site request forgery (CSRF) vulnerabilities in Moodle 2.0.x before 2.0.2 allow remote attackers to hijack the authentication of arbitrary users for requests that mark the completion of (1) an activity or (2) a course.

Moodle 2.0.x before 2.0.3 does not recognize the configuration setting that makes e-mail addresses visible only to course members, which allows remote authenticated users to obtain sensitive address information by reading a full profile page.

Moodle 2.0.x before 2.0.2 allows remote attackers to obtain sensitive information from a myprofile (aka My profile) block by visiting a user-context page.

Moodle 1.9.x before 1.9.11 and 2.0.x before 2.0.2 places an IMS enterprise enrolment file in the course-files area, which allows remote attackers to obtain sensitive information via a request for imsenterprise-enrol.xml.

The theme implementation in Moodle 2.0.x before 2.0.4 and 2.1.x before 2.1.1 triggers duplicate caching of Cascading Style Sheets (CSS) and JavaScript content, which allows remote attackers to bypass intended access restrictions and write to an operating-system temporary directory via unspecified vectors.

lib/db/access.php in Moodle 2.0.x before 2.0.4 and 2.1.x before 2.1.1 assigns incorrect capabilities to the course-creator role, which allows remote authenticated users to modify course filters by leveraging this role.

The moodle_enrol_external:role_assign function in enrol/externallib.php in Moodle 2.0.x before 2.0.4 and 2.1.x before 2.1.1 does not have an authorization check, which allows remote authenticated users to gain privileges by making a role assignment.
