MediumCVSS 6.8 · v2.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 28/100)

  • 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: 2.8% (FIRST EPSS); higher than 86.9% of all records.
  • Fixed version: IBMJava2-JRE (Red Hat:enterprise_linux:2.1::as) 1:1.3.1-17; IBMJava2-SDK (Red Hat:enterprise_linux:2.1::as) 1:1.3.1-17; java-1.5.0-ibm (Red Hat:rhel_extras:4) 1:1.5.0.5-1jpp.2.el4.

Low priority for now. Upgrade to IBMJava2-JRE (Red Hat:enterprise_linux:2.1::as) 1:1.3.1-17; IBMJava2-SDK (Red Hat:enterprise_linux:2.1::as) 1:1.3.1-17; java-1.5.0-ibm (Red Hat:rhel_extras:4) 1:1.5.0.5-1jpp.2.el4 or later.
