Noroxi assessment

Priority: Monitor (action score 27/100)

  • 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: 2.7% (FIRST EPSS); higher than 86.4% of all records.
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: org.jenkins-ci.main:jenkins-core (Maven) 2.154, 2.138.4; jenkins (Red Hat:openshift:3.11::el7) 0:2.138.4.1544416383-1.el7.

Low priority for now. Upgrade to org.jenkins-ci.main:jenkins-core (Maven) 2.154, 2.138.4; jenkins (Red Hat:openshift:3.11::el7) 0:2.138.4.1544416383-1.el7 or later.
