    Frequently Asked Questions

    What is CVE-2017-7915?

    CVE-2017-7915 is a critical-severity vulnerability tracked under the Common Vulnerabilities and Exposures program. An Improper Restriction of Excessive Authentication Attempts issue was discovered in Moxa OnCell G3110-HSPA Version 1.3 build 15082117 and previous versions, OnCell G3110-HSDPA Version 1.2 Build 09123

    Am I affected?

    Check whether your environment runs oncell_g3110-hspa_firmware, oncell_g3110-hspa, oncell_g3110-hsdpa_firmware, oncell_g3110-hsdpa, oncell_g3150-hsdpa_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-2017-7915. 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.
