CVE-2014-0123

The wiki subsystem in Moodle through 2.3.11, 2.4.x before 2.4.9, 2.5.x before 2.5.5, and 2.6.x before 2.6.2 does not properly restrict (1) view and (2) edit access, which allows remote authenticated users to perform wiki operations by leveraging the student role and using the Recent Activity block to reach the individual wiki of an arbitrary student.

Updated moodle package fixes security vulnerabilities:

In Moodle before 2.4.9, question strings were not being filtered correctly possibly allowing cross site scripting, as quiz_question_tostring can cause invalid HTML (CVE-2014-2571).

Feedback Availability dates not honored in complete.php in Moodle before 2.4.9, therefore it was possible to start a Feedback activity while it was supposed to be closed (CVE-2014-0127).

Broken access control vulnerability in Moodle before 2.4.9 with /mod/chat/chat_ajax.php, where capabilities to chat were being checked at the start of a chat, but not during, so changes were not effective immediately (CVE-2014-0122).

In Moodle before 2.4.9, there were missing access checks on Wiki pages allowing students to see pages of other students' individual wikis, through the Recent activity block (CVE-2014-0123).

In Moodle before 2.4.9, cross site scripting was possible with Flowplayer (CVE-2013-7341).

In Moodle before 2.4.9, Forum and Quiz were showing users' email addresses when settings were supposed to be preventing this (CVE-2014-0124).

In Moodle before 2.4.9, alias links to items in an Alfresco repository were provided with information that would allow someone to impersonate the file owner in Alfresco (CVE-2014-0125).

Cross Site Request Forgery in Moodle before 2.4.9 in enrol/imsenterprise/importnow.php, due to inadequate session checking when triggering the import of IMS Enterprise identities (CVE-2014-0126).
