What it is about

MariaDB ist ein relationales Datenbanksystem, das anwendungskompatibel mit MySQL ist. Ein entfernter, anonymer Angreifer kann mehrere Schwachstellen in MariaDB Java Connector ausnutzen, um Dateien zu manipulieren, einen Denial-of-Service-Zustand auszulösen oder vertrauliche Daten offenzulegen.

Under what conditions?

Over the network and without logging in. This is the most dangerous combination: attackers can scan reachable devices automatically.

What can happen in the worst case

An attacker could use the vulnerability to

• Dateien zu manipulieren
• einen Denial-of-Service-Zustand auszulösen oder vertrauliche Daten offenzulegen

Am I affected?

Affected according to the BSI:

• MariaDB MariaDB Java Connector <3.5.11
• MariaDB MariaDB Java Connector <3.4.5
• MariaDB MariaDB Java Connector <3.3.7

The installed version is usually shown under “Help → About” or in the device’s admin interface.

What helps?

Update to at least:

• MariaDB MariaDB Java Connector 3.5.11
• MariaDB MariaDB Java Connector 3.4.5
• MariaDB MariaDB Java Connector 3.3.7

Is the vulnerability already being exploited?

None of the CVEs is in the CISA catalogue of exploited vulnerabilities. That does not mean there are no attacks, only that none are documented.
