What it is about

Red Hat OpenShift ist eine "Platform as a Service" (PaaS) Lösung zur Bereitstellung von Applikationen in der Cloud. Ein entfernter, anonymer Angreifer kann mehrere Schwachstellen in Red Hat OpenShift Tempo ausnutzen, um Sicherheitsmaßnahmen zu umgehen, vertrauliche Informationen offenzulegen, Daten zu manipulieren oder einen Denial-of-Service-Zustand zu verursachen.

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

• Sicherheitsmaßnahmen zu umgehen
• vertrauliche Informationen offenzulegen
• Daten zu manipulieren oder einen Denial-of-Service-Zustand zu verursachen

Am I affected?

Affected according to the BSI:

• Red Hat Enterprise Linux
• SUSE openSUSE
• IBM InfoSphere Information Server
• IBM Integration Bus
• Red Hat OpenShift Tempo <3.9.3
• Red Hat Enterprise Linux Multicluster Global Hub <1.5.4
• IBM Cognos Analytics <12.1.3 FP2
• IBM Cognos Analytics <12.0.4 FP3

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

What helps?

Update to at least:

• Red Hat OpenShift Tempo 3.9.3
• Red Hat Enterprise Linux Multicluster Global Hub 1.5.4
• IBM Cognos Analytics 12.1.3 FP2
• IBM Cognos Analytics 12.0.4 FP3

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.
