Noroxi assessment

Priority: Monitor (action score 25/100)

  • 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: 0.22% (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 5.0 - Appliance 5.36.00.16 or later; Dell Secure Connect Gateway 5.0 - Application 5.36.00.00 or later.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Dell Secure Connect Gateway 5.0 - Appliance 5.36.00.16 or later; Dell Secure Connect Gateway 5.0 - Application 5.36.00.00 or later or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
