Updated:  May 11 2015

Impact:   Disclosure of authentication information, Disclosure of system information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information
Fix Available:  Yes  Vendor Confirmed:  Yes  

Description:   Multiple vulnerabilities were reported in Moodle. A remote user can conduct cross-site scripting attacks. A remote user can conduct cross-site request forgery attacks. A remote authenticated user can obtain potentially sensitive information.

Several scripts do not properly filter HTML code from user-supplied input before displaying the input. 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.

The mapcourse script in Feedback module is affected [CVE-2014-7830].

The 'mod/forum/settracking.php' script is affected [CVE-2014-7838].

The 'mod/lti/request_tool.php' and 'mod/lti/instructor_edit_tool_type.php' scripts are affected [CVE-2014-7836].

Some AJAX scripts and manually created pages may not send proper encoding headers, which may allow cross-site scripting attacks [CVE-2014-9059].

The generate_password() function generates weak temporary passwords [CVE-2014-7845].

A remote authenticated user without the capability to view hidden grades can access grades via the get_grades web service [CVE-2014-7831]. Versions 2.7 and 2.7.2 are affected.

A remote authenticated user can bypass capability checks in 'mod/lti/launch.php' in the LTI module [CVE-2014-7832].

A remote authenticated user can view group-level entries in the Database activity module for another group after being edited by a teacher [CVE-2014-7833].

A remote authenticated unprivileged user can access the list of available tags in the system [CVE-2014-7846].

When server load is increased, a remote user can access the IP lookup geo-mapping script [CVE-2014-7847].

A remote authenticated user can bypass a group check in the forum_get_discussions web service [CVE-2014-7834].

A remote user can directly access an internal file ('lib/phpunit/bootstrap.php') to determine the file system path [CVE-2014-7848].

Web services with a file upload function are affected [CVE-2014-7835].

A remote authenticated user that can delete pages in at least one Wiki activity in the course can modify a URL to delete pages in other Wiki pages in the same course [CVE-2014-7837].

A remote user can bypass a session key check to print arbitrary messages [CVE-2014-9060].

Petr Skoda, Dan Poltawski, Aaron Barnes, Damyon Wiese, Frederic Massart, Pamela Verret, and Sam Marshall reported these vulnerabilities.

Impact:   A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the Moodle software, 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.

A remote authenticated user can obtain potentially sensitive information.

Solution:   The vendor has issued a fix (2.5.9, 2.6.6, 2.7.3, 2.8).

The vendor's advisory is available at:
