HighCVSS 7.5 · v3.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 31/100)

  • 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: 3.6% (FIRST EPSS); higher than 89.7% of all records.
  • 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.
  • Fixed version: org.jboss.mod_cluster:mod_cluster-parent (Maven) 1.3.3.Final; hornetq-native (Red Hat:jboss_enterprise_application_platform:6::el6) 0:2.3.25-4.SP11_redhat_1.ep6.el6; hornetq-native-debuginfo (Red Hat:jboss_enterprise_application_platform:6::el6) 0:2.3.25-4.SP11_redhat_1.ep6.el6.

Low priority for now. Upgrade to org.jboss.mod_cluster:mod_cluster-parent (Maven) 1.3.3.Final; hornetq-native (Red Hat:jboss_enterprise_application_platform:6::el6) 0:2.3.25-4.SP11_redhat_1.ep6.el6; hornetq-native-debuginfo (Red Hat:jboss_enterprise_application_platform:6::el6) 0:2.3.25-4.SP11_redhat_1.ep6.el6 or later.
