Date:  Jan 19 2016
Impact:   Disclosure of authentication information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information, User access via network

Description:   Two vulnerabilities were reported in Moodle. A remote user can gain gain access to hidden courses without proper permissions. A remote user can conduct cross-site scripting attacks.

The core_enrol_get_course_enrolment_methods() and enrol_self_get_instance_info do not check user permissions when accessing hidden courses [CVE-2016-0724].

Juan Leyva reported this vulnerability.

The course management interface does not properly filter HTML code from user-supplied input before displaying the input [CVE-2016-0725]. A remote user can cause arbitrary scripting code to be executed by the target user's browser. The code will originate from the site running the Moodle software and will run in the security context of that site. As a result, the code will be able to access the target user's cookies (including authentication cookies), if any, associated with the site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user. Versions 2.8.x, 2.9.x, and 3.0.x are affected.

Oliveira Lima reported this vulnerability.

Impact:   A remote user can gain gain access to hidden courses without proper permissions.

Solution:   The vendor has issued a fix (2.7.12, 2.8.10, 2.9.4, 3.0.2).
