DESCRIPTION:
Multiple vulnerabilities have been reported in Moodle, which can be
exploited by malicious users to conduct script insertion attacks and
bypass certain security restrictions and by malicious people to
disclose certain sensitive information and conduct cross-site
scripting or cross-site request forgery attacks.

1) Input passed via the "query" parameter to tag/tag_autocomplete.php
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.

2) An error due to the application insecurely storing the IMS
enterprise enrol file (imsenterprise-enrol.xml) can be exploited to
disclose certain sensitive information.

3) Certain input is not properly sanitised by the media filter before
being used. This can be exploited to insert arbitrary HTML and script
code which will be executed in a user's browser session in context of
an affected site when the malicious data is being viewed.

Successful exploitation of this vulnerability requires
authentication.

These vulnerabilities are reported in versions prior to 1.9.11 and
2.0.2.

4) An error due to the "$CFG->forceloginforprofiles" option not being
enforced can be exploited to disclose information about course
profiles via search engine indexes or guest user access.

5) Input passed via course tags 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.

6) An error within the My Profile block when placed on pages in the
user context can be exploited to disclose private information.

7) An error due to insecure default permissions of the "teacher" role
providing delete capability can be exploited to delete courses.

These vulnerabilities are reported in versions prior to 2.0.2

8) The application allows users to perform certain actions via HTTP
requests without making proper validity checks to verify the
requests. This can be exploited to manipulate RSS feeds or mark
courses and activities as completed by tricking a user into visiting
a malicious web site while being logged in to the application.

SOLUTION:
Update to version 1.9.11 and 2.0.2.

PROVIDED AND/OR DISCOVERED BY:
1) The vendor credits gose
2, 3, 5, 6) Reported by the vendor
4) The vendor credits Amr Hourani
7) The vendor credits Patrick Pollet.
8) Reported by the vendor and Dan Poltawski
