Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: JSSE).
Noroxi assessment
Priority: Monitor (action score 21/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.27% (FIRST EPSS).
- Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
- According to CISA the attack is automatable: targets can be found by mass scanning.
- Fixed version: java-21-openjdk (AlmaLinux:10) 1:21.0.12.1.1-1.2.el10.alma.1; java-21-openjdk-demo (AlmaLinux:10) 1:21.0.12.1.1-1.2.el10.alma.1; java-21-openjdk-demo-fastdebug (AlmaLinux:10) 1:21.0.12.1.1-1.2.el10.alma.1.
Low priority for now. Upgrade to java-21-openjdk (AlmaLinux:10) 1:21.0.12.1.1-1.2.el10.alma.1; java-21-openjdk-demo (AlmaLinux:10) 1:21.0.12.1.1-1.2.el10.alma.1; java-21-openjdk-demo-fastdebug (AlmaLinux:10) 1:21.0.12.1.1-1.2.el10.alma.1 or later.
