Moodle — система управления образовательными электронными курсами

Multiple open redirect vulnerabilities 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 redirect users to arbitrary web sites and conduct phishing attacks via vectors related to (1) backup/backupfilesedit.php, (2) comment/comment_post.php, (3) course/switchrole.php, (4) mod/wiki/filesedit.php, (5) tag/coursetags_add.php, or (6) user/files.php.

calendar/managesubscriptions.php in Moodle 2.4.x before 2.4.2 does not consider capability requirements before displaying calendar subscriptions, which allows remote authenticated users to obtain potentially sensitive information by leveraging the student role.

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.

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.

YUI Cross-site Scripting (XSS) vulnerability

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.

Moodle Arbitrary File Read via Backup Functionality

Moodle vulnerable to Exposure of Sensitive Information to an Unauthorized Actor

The LTI (aka IMS-LTI) mod_form implementation in Moodle through 2.1.10, 2.2.x before 2.2.11, 2.3.x before 2.3.8, 2.4.x before 2.4.5, and 2.5.x before 2.5.1 does not properly support the sendname, sendemailaddr, and acceptgrades settings, which allows remote attackers to obtain sensitive information in opportunistic circumstances by leveraging an environment in which there was an ineffective attempt to enable the more secure values.
