Successful exploitation of this vulnerability requires permissions to export data via the database activity module. 2) An error in the web service function "core_user_update_users" resets the password when updating a user, which can be exploited to log in as a user with an empty password. 3) Multiple errors exist in the handling of access permissions in repository/coursefiles/db/access.php, repository/filesystem/db/access.php, repository/local/db/access.php, and repository/webdav/db/access.php, which can be exploited to disclose the contents of otherwise restricted repositories. 4) An error exists in the handling of access permissions in the "load_for_user()" function in lib/navigationlib.php (when "Full name format" is set to "First name" in "Site Policies"), which can be exploited to disclose users' last names on the breadcrumbs page. 5) An error exists in the handling of access permissions in the "definition()" function in grade/export/grade_export_form.php when exporting grades, which can be exploited to disclose hidden grades. Successful exploitation of this vulnerability requires permissions to export grades. 6) An error exists in the handling of access permissions in the "fill_table()" function in grade/report/overview/lib.php, which can be exploited to disclose hidden courses in the overview report. 7) An error exists in the handling of access permissions in mod/forum/index.php, which can be exploited to subscribe to forums for otherwise restricted courses. Successful exploitation of this vulnerability requires a manager account. 8) An error exists in the handling of access permissions in the "coursetag_get_tagged_courses()" function in tag/coursetagslib.php when displaying tag searches, which can be exploited to disclose hidden courses. 9) An error exists in the handling of access permissions in the "get_enrolled_users()" function in enrol/externallib.php, which can be exploited to disclose enrolled users for a course. This vulnerability is only reported in versions 2.2 through 2.2.1. The security issues and vulnerabilities are reported in versions 2.1 through 2.1.4+ and 2.2 through 2.2.1+. SOLUTION: Update to version 2.1.5 or 2.2.2.
