No further information is currently available. This vulnerability is reported in versions 2.4, 2.3 through 2.3.3+, 2.2 through 2.2.6+, and 2.1 through 2.1.9+. 2) The application does not properly verify capabilities when editing outcomes, which can be exploited to set outcomes to be a site-wide standard. Successful exploitation of this security issue requires teacher permission. This security issue is reported in versions 2.4, 2.3 through 2.3.3+, 2.2 through 2.2.6+, 2.1 through 2.1.9+, and 1.9 through 1.9.19. 3) Input passed via the "returnurl" parameter to multiple scripts is not properly verified before being used to redirect users. This can be exploited to redirect a user to an arbitrary website e.g. when a user clicks a specially crafted link to the affected script hosted on a trusted domain. List of affected scripts: http://[host]/backup/backupfilesedit.php http://[host]/comment/comment_post.php http://[host]/course/switchrole.php http://[host]/mod/wiki/filesedit.php http://[host]/tag/coursetags_add.php http://[host]/user/files.php This weakness is reported in versions 2.4, 2.3 through 2.3.3+, and 2.2 to 2.2.6+. 4) The application does not properly restrict access to the feedback comment viewing functionality, which can be exploited to view otherwise restricted feedback comments provided on other students' submissions. Successful exploitation of this vulnerability requires student permission. This vulnerability is reported in versions 2.4 and 2.3 through 2.3.3+. 5) The application allows users to perform certain actions via HTTP requests without performing proper validity checks to verify the requests. This can be exploited to e.g. send course messages when a logged-in user visits a specially crafted web page. 6) The application does not properly restrict access to certain blog posts, which can be exploited to disclose contents of otherwise restricted blog posts via related RSS feeds. The vulnerabilities #5 and #6 are reported in versions 2.4, 2.3 through 2.3.3+, and 2.2 to 2.2.6+. 7) The application does not properly verify capabilities when handling calendars, which can be exploited to delete a teacher created course level calendar subscription. Successful exploitation of this security issue requires student permission. This security issue is reported in version 2.4. SOLUTION: Update to version 2.4.1, 2.3.4, 2.2.7, 2.1.10, or 1.9.19+ weekly build (2012-12-20) or later.
