DESCRIPTION:
Multiple weaknesses, two security issues, and multiple
vulnerabilities have been reported in Moodle, where one has an
unknown impact and the others can be exploited by malicious users to
bypass certain security restrictions and by malicious people to
conduct spoofing and cross-site request forgery attacks and disclose
potentially sensitive information.
1) An unspecified error exists in the spellchecker plugin for
TinyMCE. 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.
