CVE-2011-4592

Name of the Vulnerable Software and Affected Versions Moodle versions 2.0.x through 2.0.5 Moodle versions 2.1.x through 2.1.2

Description The issue is related to the command-line cron implementation, which does not properly interact with IP blocking. This might allow remote attackers to bypass intended IP address restrictions by leveraging a configuration in which IP blocking was disabled to restore cron functionality.

Recommendations For Moodle versions 2.0.x through 2.0.5, update to version 2.0.6 or later. For Moodle versions 2.1.x through 2.1.2, update to version 2.1.3 or later.
