Technical details

The Assignment Management endpoint (modules/grades/Assignments.php) concatenates unsanitized POST array keys directly into SQL WHERE and SET clauses without parameterization. Teacher-level privileges are sufficient to reach the vulnerability through two injection points: immediate execution in the SELECT WHERE numeric position and stored injection in the UPDATE SET column position. Both boolean time-delay and error-based extraction techniques are supported.
