Moodle — система управления образовательными электронными курсами

Cross-site request forgery (CSRF) vulnerability in report/overview/report.php in the quiz module in Moodle before 1.8.13 and 1.9.x before 1.9.9 allows remote attackers to hijack the authentication of arbitrary users for requests that delete quiz attempts via the attemptid parameter.

Cross-site scripting (XSS) vulnerability in the Wiki subsystem in Moodle 2.0.x before 2.0.9, 2.1.x before 2.1.6, and 2.2.x before 2.2.3 allows remote authenticated users to inject arbitrary web script or HTML via a crafted string that is inserted into a page title.

The MNET authentication functionality in Moodle 1.9.x before 1.9.15, 2.0.x before 2.0.6, and 2.1.x before 2.1.3 allows remote authenticated users to impersonate other user accounts by using the Login As feature in conjunction with a remote MNET single sign-on capability, as demonstrated by a Mahara site.

Multiple cross-site scripting (XSS) vulnerabilities in admin/tool/task/scheduledtasks.php in Moodle 2.7.x before 2.7.1 allow remote attackers to inject arbitrary web script or HTML via vectors that trigger a crafted (1) error or (2) success message for a scheduled task.

mod/assign/locallib.php in the assignment module in Moodle 2.3.x before 2.3.7 and 2.4.x before 2.4.4 does not consider capability requirements during the processing of ZIP assignment-archive download (aka downloadall) requests, which allows remote authenticated users to read other users' assignments by leveraging the student role.

In Moodle 2.x and 3.x, the capability to view course notes is checked in the wrong context.

auth/ldap/ntlmsso_attempt.php in Moodle 2.0.x before 2.0.10, 2.1.x before 2.1.7, 2.2.x before 2.2.4, and 2.3.x before 2.3.1 redirects users from an https LDAP login URL to an http URL, which allows remote attackers to obtain sensitive information by sniffing the network.

mod/forum/user.php in Moodle 1.9.x before 1.9.16 allows remote authenticated users to obtain the names and other details of arbitrary user accounts by searching for posts.

repository/s3/S3.php in the Amazon S3 library in Moodle through 2.2.11, 2.3.x before 2.3.9, 2.4.x before 2.4.6, and 2.5.x before 2.5.2 does not verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate, related to an incorrect CURLOPT_SSL_VERIFYHOST value.

Atto in Moodle 2.8.x before 2.8.9 and 2.9.x before 2.9.3 allows remote attackers to cause a denial of service (disk consumption) by leveraging the guest role and entering drafts with the editor-autosave feature.
