Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-471: Modification of Assumed-Immutable Data (MAID), where the product does not properly protect an assumed-immutable element from being modified by an attacker. In Moodle/moodle, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

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.
