The MoodleQuickForm class in the Forms Library in lib/formslib.php in Moodle 1.9.x before 1.9.14, 2.0.x before 2.0.5, and 2.1.x before 2.1.2 does not recognize Forms API setConstant operations, which allows remote attackers to submit unexpected form content by modifying the values of constant fields.

Security readout for executives and security teams

CVE-2011-4301 affects older Moodle releases. A forms handling bug let remote users submit values that Moodle intended to keep constant. Business risk depends on which forms, workflows, and plugins used those fields. The source bundle does not establish data theft, privilege escalation, or active exploitation. Exposure is most likely on legacy Moodle deployments still running 1.9.x, 2.0.x, or 2.1.x below the fixed versions, especially internet-facing instances with form-based workflows. Current supported Moodle installations are unlikely to be affected if they include later fixes. Treat this as a legacy-platform hygiene issue unless affected Moodle versions are still exposed. If vulnerable versions remain online, schedule upgrade or retirement promptly because form integrity controls may be bypassable and the affected branches are old. Mitigation focus: Upgrade Moodle to 1.9.14, 2.0.5, 2.1.2, or later supported releases.; Review Moodle vendor guidance and the referenced fix before planning remediation.; Prioritize internet-facing or externally accessible Moodle instances..
