Moodle — система управления образовательными электронными курсами

filter/mediaplugin/filter.php in Moodle through 2.5.9, 2.6.x before 2.6.7, 2.7.x before 2.7.4, and 2.8.x before 2.8.2 allows remote authenticated users to cause a denial of service (CPU consumption or partial outage) via a crafted string that is matched against an improper regular expression.

files/externallib.php in Moodle through 2.5.9, 2.6.x before 2.6.11, 2.7.x before 2.7.8, and 2.8.x before 2.8.6 does not consider the moodle/user:manageownfiles capability before approving a private-file upload, which allows remote authenticated users to bypass intended file-management restrictions by using web services to perform uploads after this capability has been revoked.

lib/moodlelib.php in Moodle through 2.5.9, 2.6.x before 2.6.9, 2.7.x before 2.7.6, and 2.8.x before 2.8.4, when the theme uses the blocks-regions feature, establishes the course state at an incorrect point in the login-validation process, which allows remote attackers to obtain sensitive course information via unspecified vectors.

access.php in the Lesson module in Moodle 2.8.x before 2.8.2 does not set the RISK_XSS bit for graders, which allows remote authenticated users to conduct cross-site scripting (XSS) attacks via crafted essay feedback.

Moodle 2.8.x before 2.8.6 does not consider the tool/monitor:subscribe capability before entering subscriptions to site-wide event-monitor rules, which allows remote authenticated users to obtain sensitive information via a subscription request.

message/externallib.php in Moodle through 2.5.9, 2.6.x before 2.6.7, 2.7.x before 2.7.4, and 2.8.x before 2.8.2 allows remote authenticated users to bypass a messaging-disabled setting via a web-services request, as demonstrated by a people-search request.

Directory traversal vulnerability in the min_get_slash_argument function in lib/configonlylib.php in Moodle through 2.5.9, 2.6.x before 2.6.8, 2.7.x before 2.7.5, and 2.8.x before 2.8.3 allows remote authenticated users to read arbitrary files via a .. (dot dot) in the file parameter, as demonstrated by reading PHP scripts.

login/token.php in Moodle through 2.5.9, 2.6.x before 2.6.9, 2.7.x before 2.7.6, and 2.8.x before 2.8.4 allows remote authenticated users to bypass a forced-password-change requirement by creating a web-services token.

tag/user.php in Moodle through 2.5.9, 2.6.x before 2.6.9, 2.7.x before 2.7.6, and 2.8.x before 2.8.4 does not consider the moodle/tag:flag capability before proceeding with a flaginappropriate action, which allows remote authenticated users to bypass intended access restrictions via the "Flag as inappropriate" feature.

Cross-site scripting (XSS) vulnerability in mod/quiz/report/statistics/statistics_question_table.php in Moodle through 2.5.9, 2.6.x before 2.6.9, 2.7.x before 2.7.6, and 2.8.x before 2.8.4 allows remote authenticated users to inject arbitrary web script or HTML by leveraging the student role for a crafted quiz response.
