What it is about

Docker ist eine Open-Source-Software, die dazu verwendet werden kann, Anwendungen mithilfe von Betriebssystemvirtualisierung in Containern zu isolieren. Ein lokaler Angreifer kann mehrere Schwachstellen in docker ausnutzen, um beliebigen Programmcode mit Administratorrechten auszuführen, einen Denial-of-Service-Zustand zu verursachen oder Daten zu manipulieren.

Under what conditions?

Only with access to the device or an account on it. Often the second step after a phishing email.

What can happen in the worst case

An attacker could use the vulnerability to

  • beliebigen Programmcode mit Administratorrechten auszuführen
  • einen Denial-of-Service-Zustand zu verursachen oder Daten zu manipulieren

Am I affected?

Affected according to the BSI:

  • Debian Linux
  • Amazon Linux 2
  • Red Hat Enterprise Linux
  • SUSE Linux
  • SUSE openSUSE
  • IBM MQ operator
  • Open Source docker <29.5.1
  • Dell Secure Connect Gateway <5.36.00.16

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

What helps?

Update to at least:

  • Open Source docker 29.5.1
  • Dell Secure Connect Gateway 5.36.00.16

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.
