Frequently Asked Questions
What is CVE-2016-9361?
CVE-2016-9361 is a critical-severity vulnerability tracked under the Common Vulnerabilities and Exposures program. An issue was discovered in Moxa NPort 5110 versions prior to 2.6, NPort 5130/5150 Series versions prior to 3.6, NPort 5200 Series versions prior to 2.8, NPort 5400 Series versions prior to 3.11, NPort
Am I affected?
Check whether your environment runs nport_5100_series_firmware, nport_5110, nport_5130, nport_5150, nport_5200_series_firmware. If you operate any of those, treat yourself as in scope until you have evidence otherwise. A Vulnios scan will identify the exact assets carrying the affected version.
How urgent is the response?
Critical: do not wait for your normal patch cycle. Verify exposure today, apply the vendor patch immediately, and add detection rules for any post-exploit indicators.
How do I remediate?
Apply the vendor patch listed in the upstream advisory linked under Sources. If the patch is not yet available, follow the vendor-supplied workaround (often a config flag or feature disable) and add detections for the published exploit pattern in your SIEM. Re-scan after the patch lands to confirm the finding clears.
Where can I track exploitation activity?
Watch CISA's Known Exploited Vulnerabilities catalog for CVE-2016-9361. Cross-reference with public exploit databases and your own SIEM/IDS for indicator-of-compromise patterns. Vulnios tracks KEV status automatically and surfaces it on the asset findings view.
How does Vulnios help with this?
Vulnios continuously cross-references your asset inventory against the live CVE feed (NVD, vendor advisories, CISA KEV, and curated OSINT). When a new CVE matches your environment, you get a prioritized finding with the severity, KEV status, exploit-prediction (EPSS), and a direct path to the vendor patch. You can start a free scan from the homepage.
