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:
- Debian Linux
- Amazon Linux 2
- Open Source OpenJDK
- Red Hat Enterprise Linux
- Oracle Java SE 26.0.2
- Oracle Java SE 8u503
- Oracle Java SE 8u503-perf
- Oracle JavaFX 21.0.12
- Oracle JavaFX 25.0.4
- Oracle JavaFX 27
- Oracle Java SE 11.0.32.1
- Oracle Java SE 17.0.20.1
and 7 more
The installed version is usually shown under “Help → About” or in the device’s admin interface.
What helps?
Update to at least:
- Amazon Corretto 8.512.08.1
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.
