Moodle 2.4.x < 2.4.9 Multiple Vulnerabilities

Medium

Synopsis

The remote web server is hosting a web application that is vulnerable to multiple attack vectors.

Description

The remote web server hosts Moodle, an open-source course management system. Versions of Moodle 2.4.x prior to 2.4.9 are exposed to the following vulnerabilities :

- A flaw exists in the 'mod/chat/chat_ajax.php' script that is due to the program checking capabilities at the start of a chat and not during a chat. This will cause changes to not be enforced immediately. (CVE-2014-0122) - A flaw exists that is due to the program failing to perform access checks on certain wiki pages. This may allow an unauthorized remote attacker to gain access to potentially sensitive information from other user's individual wikis via the recent activity block. (CVE-2014-0123) - A flaw exists in the 'mod/forum/renderer.php' script that is due to Forum exposing user's email addresses regardless of security settings. This may allow an authenticated remote attacker to gain access to email information. (CVE-2014-0124) - A flaw exists that is triggered when handling alias links to items in an Alfresco repository. This may allow a remote attacker to gain access to session key information and subsequently impersonate a file owner. (CVE-2014-0125) - A flaw exists as HTTP requests to 'enrol/imsenterprise/importnow.php' do not require multiple steps, explicit confirmation, or a unique token when performing certain sensitive actions. By tricking a user into following a specially crafted link, a context-dependent attacker can perform a Cross-Site Request Forgery (CSRF / XSRF) attack causing the victim to import IMS Enterprise identities. (CVE-2014-0126) - A flaw exists in 'mod_feedback' that is due to the program failing to restrict a user from starting a Feedback activity while Feedback supposed to be closed. This may allow a remote attacker to bypass restrictions on Feedback Availability. (CVE-2014-0127) - A flaw exists that allows a cross-site scripting (XSS) attack. This flaw exists because the 'quiz_question_tostring()' function in the 'mod/quiz/editlib.php' script does not validate input before returning it to users. This may allow a remote attacker to create a specially crafted request that would execute arbitrary script code in a user's browser session within the trust relationship between the browser and the server. (CVE-2014-2571)

Solution

Upgrade to Moodle version 2.4.9 or later.
