Vulnerability from fkie_nvd - Published: 2012-07-20 10:40 - Updated: 2026-06-16 23:35
Severity
Summary
The command-line cron implementation in Moodle 2.0.x before 2.0.6 and 2.1.x before 2.1.3 does not properly interact with IP blocking, which might allow remote attackers to bypass intended IP address restrictions by leveraging a configuration in which IP blocking was disabled to restore cron functionality.
