Moodle 2.3.x < 2.3.1 Multiple Vulnerabilities

low Nessus Network Monitor Plugin ID 9406

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 2.3.x prior to 2.3.1 are exposed to the following vulnerabilities :

 - A flaw exists that is triggered when an error occurs in the 'file_save_draft_area_files()' function in files where shortcuts or alias are not permitted. This may allow an attacker to more easily compromise a user's system via uploading files that are not properly validated. (CVE-2012-3387)
 - A flaw exists that is triggered when an error occurs in the 'is_enrolled()' function in the 'lib/accesslib.php script' after a user record has been cached. This may allow a remote attacker to bypass access restrictions. (CVE-2012-3388)
 - A flaw exists that allows a remote cross-site scripting (XSS) attack. This flaw exists because the application does not validate input passed via multiple unspecified parameters in the LTI (External tool) module upon submission to the 'mod/lti/typessettings.php' script. This may allow a user to create a specially crafted request that would execute arbitrary script code in a user's browser within the trust relationship between their browser and the server. (CVE-2012-3389)
 - A flaw exists that is triggered when the program fails to properly restrict access to files embedded by a block. This may allow a remote attacker to bypass access restrictions and gain access to arbitrary files. (CVE-2012-3390)
 - A flaw exists that allows a remote cross-site scripting (XSS) attack. This flaw exists because the application does not validate input passed via certain unspecified fields when administrating cohorts before returning it to the user. This may allow a user to create a specially crafted request that would execute arbitrary script code in a user's browser within the trust relationship between their browser and the server. (CVE-2012-3396)
 - A flaw exists that may lead to an unauthorized information disclosure. The issue is triggered when the Restrict Access conditions improperly overwrite group settings. This will display potentially sensitive group activities to a remote attacker. (CVE-2012-3397)

Solution

Upgrade to Moodle version 2.3.1 or later.
