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

1) An error exists in the handling of access permissions and can be
exploited to disclose user details.

Successful exploitation of this vulnerability requires a teacher
account.

2) An error when reading recent conversations can be exploited to
read other users' messages via a specially crafted URL.

3) An error when adding questions to a quiz does not check the
"question:use" permission, which can be exploited to add questions to
a quiz.

4) An error exists in the handling of access permissions in the
question bank, which can be exploited to save questions.

5) An error exists in the handling of access permissions, which can
be exploited to edit read-only activity entries.

6) An error can be exploited to modify user permissions.

Successful exploitation of this vulnerability requires a teacher
account.

7) Certain input when saving wiki page titles is not properly
sanitised 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.

8) Input passed via the "name" parameter to
admin/webservice/service.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.

9) Certain input passed to blog/index.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.

10) Certain input when adding a calendar event is not properly
sanitised before being used in SQL queries. This can be exploited to
manipulate SQL queries by injecting arbitrary SQL code.

11) Input passed via the "idnumber" parameter to cohort/edit.php is
not properly sanitised 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.

12) An error exists in the handling of access permissions, which can
be exploited to overwrite other users' activity presets.

13) An error exists in the handling of access permissions, which can
be exploited to create calendar entries.

Vulnerabilities #9, #10, and #14 are reported in versions 1.9 through
1.9.17+, vulnerabilities #1-4 are reported in versions 2.2 through
2.2.2+ and 2.1 through 2.1.5+, vulnerabilities #5-8, #11, #12, and
#14 are reported in versions 2.2 through 2.2.2+, 2.1 through 2.1.5+,
and 2.0 through 2.0.8+.
