Moodle — система управления образовательными электронными курсами

blog/rsslib.php in Moodle 2.2.x before 2.2.7, 2.3.x before 2.3.4, and 2.4.x before 2.4.1 allows remote attackers to obtain sensitive information from site-level blogs by leveraging the guest role and reading an RSS feed.

Multiple cross-site request forgery (CSRF) vulnerabilities in user/messageselect.php in the messaging system in Moodle 2.2.x before 2.2.7, 2.3.x before 2.3.4, and 2.4.x before 2.4.1 allow remote attackers to hijack the authentication of arbitrary users for requests that send course messages.

report/outline/index.php in Moodle 2.2.x before 2.2.7, 2.3.x before 2.3.4, and 2.4.x before 2.4.1 does not properly enforce the moodle/user:viewhiddendetails capability requirement, which allows remote authenticated users to discover a hidden lastaccess value by reading an activity report.

badges/external.php in Moodle 2.5.x before 2.5.2 does not properly handle an object obtained by unserializing a description of an external badge, which allows remote attackers to conduct PHP object injection attacks via unspecified vectors, as demonstrated by overwriting the value of the userid parameter.

YUI Cross-site Scripting (XSS) vulnerability

Directory traversal vulnerability in repository/filesystem/lib.php in Moodle through 2.2.11, 2.3.x before 2.3.10, 2.4.x before 2.4.7, and 2.5.x before 2.5.3 allows remote authenticated users to read arbitrary files via a .. (dot dot) in a path.

Moodle Arbitrary File Read via Backup Functionality

The Shibboleth authentication plugin in auth/shibboleth/index.php in Moodle through 2.3.11, 2.4.x before 2.4.11, and 2.5.x before 2.5.7 does not check whether a session ID is empty, which allows remote authenticated users to hijack sessions via crafted plugin interaction.
