MariaDB 3.4.0 < 3.4.10

medium Nessus Plugin ID 367984

Synopsis

The remote database server is affected by a vulnerability.

Description

The version of MariaDB installed on the remote host is prior to 3.4.10. It is, therefore, affected by a vulnerability as referenced in the GHSA-fmq9-qjxj-qpf7 advisory.

- MariaDB Connector/C is a C and C++ client library for connecting applications to MariaDB and MySQL databases. From 3.4.1 until 3.4.10, the MariaDB Connector/C libmariadb Zero-Configuration SSL authentication-switch logic checked certificate trust failure but did not reject a TLS hostname verification mismatch before selecting a non-hashing authentication plugin. An active man-in-the-middle attacker with a valid certificate for another hostname could request mysql_clear_password and obtain the database password inside the attacker-controlled TLS connection. Other MariaDB connectors are not affected. This issue is fixed in version 3.4.10. (CVE-2026-107819)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to MariaDB version 3.4.10 or later.
