Moodle 2.3.x < 2.3.2 Multiple Vulnerabilities

The remote web server hosts Moodle, an open-source course management system. Versions of Moodle 2.3.x prior to 2.3.2 are exposed to the following vulnerabilities :

• A flaw exists that may allow a remote attacker to manipulate parameters for the ‘repository/repository_ajax.php script’. This will allow the attacker to bypass restrictions and upload a file that is larger than the allotted size. (CVE-2012-4400)
• A flaw exists that is triggered when the application fails to properly restrict access to certain topic functions. This may allow a remote attacker to show or hide topics, as well as set a current topic. (CVE-2012-4401)
• A flaw exists that is triggered when the ‘webservice/lib.php’ script fails to properly limit tokens to the service that issued them. This may allow a remote attacker to use a token intended for one service to gain access to arbitrary other external services. (CVE-2012-4402)
• A flaw exists that may lead to an unauthorized information disclosure. The issue is triggered when a remote attacker creates a malformed request for the ‘yui_combo.php’ script, which discloses the software’s installation path resulting in a loss of confidentiality. While such information is relatively low risk, it is often useful in carrying out additional, more focused attacks. (CVE-2012-4403)
• A flaw exists that may lead to an unauthorized information disclosure. The issue is triggered when the ‘lib/filelib.php’ script does not properly check the publication state of blog files. This may allow a remote attacker to gain access to the embedded files of the blog before it is published. (CVE-2012-4407)
• A flaw exists when permissions are not properly verified on the reset page. This may allow a remote attacker to reset a course via the reset page. (CVE-2012-4408)
