HighCVSS 7.5 · v2.0—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: 3.1% (FIRST EPSS); higher than 88.3% of all records.
  • No special conditions are required; it is repeatable.
  • Fixed version: plone (PyPI) 4.0.4, 4.0.1; conga (Red Hat:rhel_cluster:4) 0:0.11.2-4.el4.2; conga-debuginfo (Red Hat:rhel_cluster:4) 0:0.11.2-4.el4.2.

Low priority for now. Upgrade to plone (PyPI) 4.0.4, 4.0.1; conga (Red Hat:rhel_cluster:4) 0:0.11.2-4.el4.2; conga-debuginfo (Red Hat:rhel_cluster:4) 0:0.11.2-4.el4.2 or later.
