Moodle — система управления образовательными электронными курсами

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 comments operations.

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 error-message functionality in Moodle 1.9.x before 1.9.13, 2.0.x before 2.0.4, and 2.1.x before 2.1.1 does not ensure that a continuation link refers to an http or https URL for the local Moodle instance, which might allow attackers to trick users into visiting arbitrary web sites via unspecified vectors.

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.

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

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.

Multiple cross-site scripting (XSS) vulnerabilities in the course-tags functionality in tag/coursetags_more.php in Moodle 2.0.x before 2.0.2 allow remote attackers to inject arbitrary web script or HTML via the (1) sort or (2) show parameter.

Cross-site scripting (XSS) vulnerability in the Spike PHPCoverage (aka spikephpcoverage) library, as used in Moodle 2.0.x before 2.0.2 and other products, allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.
