This security issue is reported in version 2.3. 2) An error when verifying capabilities of cached users in the "is_enrolled()" function (lib/accesslib.php) can be exploited to bypass certain security restrictions. 3) Certain input passed to the LTI (External tool) module is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site. The vulnerabilities #2 and #3 are reported in versions 2.2 through 2.2.3+ and 2.3. 4) The application does not properly restrict access to files embedded in a block (e.g. HTML block) and can be exploited to access otherwise restricted files. 5) An error when handling Q&A forum posts via RSS feeds can be exploited to disclose otherwise restricted information. 6) An error when verifying capabilities in forum subscriptions can be exploited to unsubscribe from unsubscription restricted forums. The vulnerabilities #4 through #6 are reported in versions 2.1 through 2.1.6+ and 2.2 through 2.2.3+. 7) An error when handling redirections during the login process via LDAP can lead to a redirection from the HTTPS to the HTTP protocol. 8) Certain input passed to the administration of cohorts is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site. 9) An error when handling "Restrict Access" conditions can be exploited to display a group restricted activity. The vulnerabilities #7 through #9 are reported in versions 2.0 through 2.0.9+, 2.1 through 2.1.6+, 2.2 through 2.2.3+, and 2.3. 10) Certain input passed via the Feedback module is not properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code. This vulnerability is reported in versions 2.0 through 2.0.9+, 2.1 through 2.1.6+, and 2.2 through 2.2.3+. SOLUTION: Update to version 2.0.10, 2.1.7, 2.2.4, or 2.3.1.
