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: 0.23% (FIRST EPSS).
  • 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: Dell Secure Connect Gateway (SCG) Policy Manager 5.36.00.16 or later.

Low priority for now. Upgrade to Dell Secure Connect Gateway (SCG) Policy Manager 5.36.00.16 or later or later.
