Moodle — система управления образовательными электронными курсами

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.

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.

Cross-site request forgery (CSRF) vulnerability in Moodle 1.9.x before 1.9.11 allows remote attackers to hijack the authentication of unspecified victims for requests that modify an RSS feed in an RSS block.

The default configuration of Moodle 2.0.x before 2.0.2 has an incorrect setting of the moodle/course:delete capability, which allows remote authenticated users to delete arbitrary courses by leveraging the teacher role.

Multiple cross-site scripting (XSS) vulnerabilities in lib/weblib.php in Moodle 1.9.x before 1.9.12 allow remote attackers to inject arbitrary web script or HTML via vectors related to URL encoding.

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.

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 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.

comment/lib.php in Moodle 2.0.x before 2.0.4 and 2.1.x before 2.1.1 does not properly restrict comment capabilities, which allows remote attackers to post a comment by leveraging the guest role and operating on a front-page activity.

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.
