The web services implementation in Moodle 2.0.x before 2.0.6 and 2.1.x before 2.1.3 does not properly consider the maintenance-mode state and account attributes during login attempts, which allows remote authenticated users to bypass intended access restrictions by connecting to a webservice server.

Security readout for executives and security teams

CVE-2011-4590 affects old Moodle 2.0.x and 2.1.x releases. Authenticated users could connect through Moodle web services in situations where maintenance mode or account restrictions should have blocked access. This is an access-control failure, not evidence of unauthenticated takeover. Exposure is likely limited to organizations still running Moodle 2.0.x before 2.0.6 or 2.1.x before 2.1.3 with web services enabled. Modern Moodle deployments are unlikely to be affected unless legacy instances remain online. Treat this as a legacy-system hygiene issue with moderate urgency. It is most important where old Moodle instances still support students, staff, or customers and web services remain enabled. Mitigation focus: Upgrade affected Moodle 2.0.x systems to 2.0.6 or later.; Upgrade affected Moodle 2.1.x systems to 2.1.3 or later.; Check Moodle vendor guidance for any branch-specific remediation notes..
