Уязвимость перехвата данных и выполнения SQL-команд в MariaDB при подключении локальных клиентов через именованные каналы на Windows
Описание
В MariaDB на Windows существует уязвимость, которая позволяет злоумышленнику, обладающему возможностью выполнять код на сервере, перехватывать соединения локальных клиентов через именованные каналы. Это происходит из-за некорректного дескриптора безопасности, что позволяет злоумышленнику выступать в роли посредника, получая доступ ко всем передаваемым между клиентом и сервером данным и исполнять SQL-команды от имени подключенного пользователя.
Затронутые версии ПО
- MariaDB Server версий до 10.1.48
- MariaDB Server 10.2.x до 10.2.35
- MariaDB Server 10.3.x до 10.3.26
- MariaDB Server 10.4.x до 10.4.16
- MariaDB Server 10.5.x до 10.5.7
Тип уязвимости
Подмена и перехват данных (атака Man-in-the-middle)
Дополнительная информация
Эта уязвимость существует в результате недостаточного устранения атаки, связанных с CVE-2019-2503, и специфична для MariaDB. Таким образом, CVE-2020-28912 не относится к другим вендорам, которые также были изначально затронуты CVE-2019-2503.

With MariaDB running on Windows, when local clients connect to the server over named pipes, it's possible for an unprivileged user with an ability to run code on the server machine to intercept the named pipe connection and act as a man-in-the-middle, gaining access to all the data passed between the client and the server, and getting the ability to run SQL commands on behalf of the connected user. This occurs because of an incorrect security descriptor. This affects MariaDB Server before 10.1.48, 10.2.x before 10.2.35, 10.3.x before 10.3.26, 10.4.x before 10.4.16, and 10.5.x before 10.5.7. NOTE: this issue exists because certain details of the MariaDB CVE-2019-2503 fix did not comprehensively address attack variants against MariaDB. This situation is specific to MariaDB, and thus CVE-2020-28912 does NOT apply to other vendors that were originally affected by CVE-2019-2503.
