What it is about

Die Java Platform, Standard Edition (SE) ist eine Sammlung von Java-APIs (JDK) und der Java Laufzeit Umgebung (JRE). Ein entfernter, anonymer oder authentisierter Angreifer kann mehrere Schwachstellen in Oracle Java SE ausnutzen, um die Vertraulichkeit, Integrität und Verfügbarkeit zu gefährden.

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

• die Vertraulichkeit
• Integrität
• Verfügbarkeit zu gefährden

Am I affected?

Affected according to the BSI:

• IBM Java
• IBM AIX 7.3
• IBM VIOS 4.1
• Debian Linux
• IBM WebSphere Service Registry and Repository 8.5
• Amazon Linux 2
• IBM AIX 7.2
• IBM Tivoli Business Service Manager
• Open Source OpenJDK
• Red Hat Enterprise Linux
• IBM Tivoli Netcool/OMNIbus
• IBM Tivoli Monitoring

and 32 more

What helps?

Update to at least:

• Amazon Corretto 11.0.32.10.1
• Amazon Corretto 8.504.01.1
• IBM Semeru Runtime 8.0.504.0
• IBM Semeru Runtime 11.0.32.10
• IBM Semeru Runtime 17.0.20.10
• IBM Semeru Runtime 21.0.12.10
• IBM Semeru Runtime 25.0.4.10
• IBM Semeru Runtime 26.0.2.10

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.
